NEC's 3000 Series SDH (Synchronous Digital Hierarchy)Microwave Radio Systems are designed to provide highquality SDH radio links. They can operate in frequencybands from 4 to 13 GHz for long-haul transmission.NEC's SDH Radio transmits one STM-1 155 Mbit/ssignal plus optional wayside signals.

The most efficient modulation techniques are used in fullcompliance with standard RF channel spacings asrecommended by ITU-R.

30 MHz spacing : 128 QAM40 MHz spacing : 64 QAM

Therefore, NEC's SDH radio systems allow users tocontinue operation without any modifications to existingfrequency allocations.

Terminal station equipment provides an STM-1 interface.An optional 2 Mbit/s wayside signal, DCC/ E1/ E2 (SOH)signal and digital service channel (DSC) signal can bedropped and inserted at either terminal or repeaterstations. The system can be expanded to an N+1protected system (N≤11). Moreover, the number ofchannels in the RF band can be further doubled byadopting dual polarisation transmission in the long-haulsystem.

Dual polarization co-channel transmission can berealized with a fully digital cross polarization interferencecanceller (XPIC).

The STM-1 radio system is part of NEC's SDH Family,adopting the same single design concept. The SDHFamily includes a wide variety of transmission systems,such as the add-drop multiplexer, as well as an NMS.This wide variety of systems opens up a full range ofconfigurations for numerous applications. For example aself-healing SDH ring can be constructed by combiningNEC's add-drop multiplexers and the 3000 Series SDHradio.

Network Management features are designed inaccordance with among others ITU-T Rec. M.3010 andG.784, and therefore enable interconnection with a TMN-based network management system (NMS).

Throughout the SDH radio system, NEC's own advancedtechnologies are used. Intensive use of MicrowaveIntegrated Circuits (MIC's) and Hybird IC's (HIC's) makesthe TRP durable and compact. Also, custom madelarge-scale integrated circuits (LSI's) are applied. Forexample, new digital MODEM is incorporated in a singleLSI chip, specially developed by NEC. Furthermore, low-power high-speed complementarymetal oxide semiconductor (CMOS) LSI's are extensivelyused, making the equipment more compact and highlyreliable, which reduces the power consumption.Operation, Administration, Maintenance & Provisioning(OAM&P) performance and functionality are easilyupgraded using software download facilities.

NEC can offer a complete transmission network system,including radio, multiplex and network managementsystem. Complete factory integration, customer training,warranty and after sales support are available.

Fig.1 SDH Network Application

SDH RADIO NETWORKSDH RADIO NETWORK

All NEC NE's are fully SDH compatible and conform tothe relevant ITU-R and ITU-T Recommendations andEuropean Telecommunications Standards (ETS).

Various system applications such as N+1 FrequencyDiversity (FD) protection switching system are available.The system can easily be expanded by adding modulesand/or subracks to the existing configuration to increasetransmission capacity. The maximum protectedtransmission capacity is 11+1. The N+1 protectionswitchover is hitless, therefore switchover operation iserror-free.

Fully digital modem with Decision Feedback Equaliser(DFE) is integrated into NEC's highly reliable customisedLSI.

Multi-Level Coding Modulation (MLCM) is applied to128QAM systems and MCLM with Reed Solomon (RS)coding is applied to 64QAM systems. This ensures besterror performance. [MLCM]- Low cording redundancy (It enables additional Wayside (WS) channel transmission.)[MLCM+RS]- Excellent cording gain- Improvement of residual BER

A high performance DFE effectively reduces inbanddispersive amplitude and delay distortions caused bymulti-path fading and comes as standard. It providesexcellent minimum and non-mininum signatureperformance.

Applying an Automatic Transmit Power Control (ATPC)system prevents interference to neighbouring systems,improves residual BER performance, alleviates upfadeproblems and reduces system power consumption.NEC's ATPC range is -12 to +2 dB.

Dual polarisation co-channel transmission can berealised with NEC's fully digital cross polarisationinterference canceller (XPIC). This doubles thefrequency efficiency and can be implemented for both 30MHz and 40 MHz band plans.

Contiguous type Branching Circuits (BR CKT) is mostsuitable filter circuit in case the following condition.- Minimum adjacent frequency separation(30 MHz or 40 MHz)

- Maximum transmission capacity(Dual polarization co-channel transmission)

The contiguous type BR CKT eliminates the need for anRF hybrid that would be required for the minimumadjacent frequency separation using a circulator type BRCKT.

The SD IF combiner incorporates both In-Phase (IP) andMinimum In-band Dispersion (MID) combining. MID cansuppress in band dispersion.The IF combiner also provides inbuilt delay electricalDADE.

The system can be equipped with an electrical or anoptical STM-1 interface for each channel. The optical interface is available for two different cablelengths: intra-office or long haul inter-office applications.

Redundant (1+1) optical interface is available for eachradio bearer. Required when connecting to a protectedFOTS or another NEC's terminal radio for extra systemavailablity.

For STM-1 electrical interface, all radio bearers comewith a main and standby code conversion card with abipolar switch. This ensures greater radio interfacereliability and better overall system availibilty in thenetwork.

In addition to the main traffic signal, 1 x (192 kbit/s or 64kbit/s) + 4 x 64 kbit/s DSC's and one or two (2 or1.5Mbit/s) WS channel(s) can be dropped and insertedat any terminal and repeater radio station. Thesechannels are transported in the RFCOH.

Built-in OAM&P facilities enable monitoring and controlof external equipment such as housekeeping facilities viaa parallel interface. Performance monitoring is built-in,including:• Performance parameters as in ITU-T G.826• Registration of the number of protection switchover

operations (for 1+1 and N+1)• Accumulation of the failed time for individual regular

channels.The operator can perform monitoring and controlfunctions, by using the LCT (Local Craft Terminal), or byusing the MS3201 Network Management System (NMS).
