This document “documents” the version 0.85 release of the MATLAB CM code. It does not reflect any changes made to the channel model parameters after about 5 November 2006.

Overloaded Channel Models

Model Environment

CM1.1 TX: 360, RX: 15

CM1.2 TX: 60, RX: 15

CM1.3 TX: 30, RX: 15

CM1.4 TX: 15, RX: 15

CM1.5 TX: 360, RX: 15

Model Environment

CM3.1 TX: 30, RX: 30

CM3.2 TX: 60, RX: 60

Model Environment

CM9.1 TX: 30, RX: 30

CM9.2 TX: 60, RX: 60

CM9.3 TX: 360, RX: 21 dBi

Question: Is this approach acceptable to the committee?

In addition to the original 8 channel environments, the overloaded CMs now give us 15 channel models. At 100 realizations per environment (typical) this gives the potential for 1,500 channel impulse responses. Just FYI.

The complete list of parameters used in this report can be summarized as follows: 1. PL0, PL at 1m distance 2. n, PL exponent 3. s shadowing standard deviation 4. , inter-cluster (cluster) arrival rate 5. , intra-cluster (ray) arrival rate 6. , inter-cluster (cluster) decay rate 7. , intra-cluster (ray) decay rate 8. c, cluster lognormal standard deviation 9. r, ray lognormal standard deviation 10. , angle spread 11. L , average number of clusters 12. d, Tx-Rx separation, h1, Tx height, h2 Rx height, GT, Tx gain, GR, Rx gain, K, Rician

factor, , average power of the first ray of the first cluster (for combined two path and S-V model)

Parameters in #12 are currently not used in the MATLAB code. All clusters are generated as relative energy and not absolute energy.

Source: 15-06-0195-04-003c

} These first 3 parameters are stored in the data base but not used in the simulation.Is shadowing part of the link budget or should it be included in the simulation?

d, Tx-Rx separation, h1, Tx height, h2 Rx height, GT, Tx gain, GR, Rx gain, k, ray Rician factor, , average power of the first ray of the first cluster (for combined two path and S-V model)

Impulse Response Truncation

% truncate impulse response to the -40 dB point

z_max=max(max(abs(ImpDt)));

for index_cn=1:NumChannels

IM_done=0;

for index=length(ImpDt):-1:1 % work backwards thru vector

if IM_done==0

if abs(ImpDt(index,index_cn))>z_max/1e2

index_max(index_cn)=index; % search for largest index that gives -40 dB

IM_done=1;

end

end

end

end

ImpDtTrunc=ImpDt(1:max(index_max),:); % truncate by using the largest index

Discrete Time Impulse Response Truncation Routine – prevents excessively long impulse responses containing little energy

Questions to be Resolved

Nov 2006


doc.: IEEE 802.15-06/0459r2

Submission

1. In document 15-06-0400-01, there are currently 5 parametric representations of CM1, 2 representations of CM3, and 3 representations of CM9. For this code release, these multiple representations are denoted as CM1.1, CM1.2, CM1.3, CM1.4, CM1.5, CM3.1, CM3.2, CM9.1, CM9.2, CM9.3. The committee needs to tell me how to deal with multiple parametric representations of the same channel model environment. Should I leave it as I have it now?

Bring to 06/483r0 under “unresolved issues”

2. I’ve derived the missing NLOS models from existing LOS models. Specifically I‘ve generated CM2 from CM1 and CM6 from CM5. My question is: “When generating CM2, which of the 5 representations of CM1 should I use”?


3. Each ray is generated with a corresponding AoA. This AoA can be used for either spatial filtering, antenna pointing, or both. I need guidance as to what the committee wants to do. An option is just to leave it the way I currently have it.

Bring to technical requirement document

4. Currently 3 things needed to be input before an impulse response can be generated. These are the antenna pattern, the pointing direction and the sample rate. Are these going to be specified by the committee or by the proposer.

Bring to technical requirement document

Questions for the Committee

Nov 2006


doc.: IEEE 802.15-06/0459r2

Submission

5. There are a number of S-V parameters that are currently missing. What can be done about these?


6. Traditionally, standards committees generate a “golden set” of impulse responses for all proposers to use. We have the option of generating a “golden set” of clusters for all proposers to use. The clusters would be loaded and the spatial filtering and sample rate would be entered by the user. Does the committee want to do it this way?

Generate one set without spatial filtering. And possibly additional sets with spatial filtering

7. Currently I do not having shadowing in the code. TG3a typically applied several dB of random shadowing. Does the committee want to include this? Should it be part of the link budget? Is it really necessary?

The group does not consider shadowing effect in the Matlab code

8. Currently all LOS impulse responses start at T=0. TG3a actually had a random dither on the LOS starting time. The code is already set up to accommodate a LOS time dither but it is not currently being implied. What is the opinion of the committee? Does this matter? Should I leave it as is?

The group does not need to reflect this.

9. Does the committee concur with truncating the impulse response to the -40 dBr point?

-30 dB shall be used.

*** Version Release 0.85 - This is Draft Code and is NOT to be Used for Proposal Analysis ***

Known problems for this 9 November 2006 release:

1. S-V parametric parameters are known to be incomplete for some of the channel models

2. Impulse responses have not been verified by the committee

3. Comments & documentation throughout the code is incomplete

4. There are several MATLAB warnings which I need to resolve

5. I can not gurarantee that the code will not crash for this release

[note: if possible, please send me the CM cluster files that crashed]

Warning: you must generate an impulse response, via menu option 2, before you can analyze it.

If the program crashes at this point, it is probably because the impulse response has not been generated.
