AbstractThis contribution presents the results of calculations establishing the coupling/isolation between an 802.22 WRAN Consumer Premise Equipment (CPE) terminal and a nearby DTV receiving installation. The DTV receiving characteristics are based on the FCC-OET Bulletin 69 which gives the basis for planning DTV broadcasting in the US. The amount of coupling/isolation between the two terminals is found from a detailed calculation of the horizontal and vertical patterns of the two antennas which are then applied to the detailed calculation of the on-axis and off-axis co-polar and cross-polar coupling.

DTV reception parameters

Noise limited contour

41 dB(uV/m)

Field strength at noise limited contour:Field = 41 + 20*log(615/F) (dBμV/m) where F is the frequency of the TV channel in MHz

Omni antenna aperture = λ2/4π (m2)

= (300/F)2/4π (m2)

Aap = 10*log((300/F)2/4π) (dBm2)

Antenna gain = (10 + 2.15) dBi

Downlead loss = 4 dB

Power at the input of the DTV receiver:

Pinput = Field -145.8 + Aap+ 12.15 - 4 (dBW)

= -83.9 dBm

• Co-polar coupling:

PowerRXco = 10*log(10(GtxH+GrxH) +10(GtxV+GrxV)) + F

• Cross-polar coupling:

PowerRXcross = 10*log(10(GtxH+GrxV) +10(GtxV+GrxH)) + F

Where F is the normalization factor to produce the maximum on-axis coupling when the two antennas are aligned:

F= PowerRX - GtxH-GrxH

Conclusions• The DTV receiving installation model for edge of contour reception, as defined by

the FCC OET, is used to explore the worst case scenario for interference from a nearby WRAN CPE.

• For the case of alternate channel use, the WRAN CPE antenna is assumed to be located at 10 m horizontally from the closest DTV receiving antenna.

• Coupling between a 4 W EIRP CPE and a DTV receiving installation is calculated for all combinations of antenna orientations using the 3D transmit and receive antenna patterns when the two antennas are both horizontal (co-polar case) and when the transmit antenna is turned vertically (cross-polar case).

• It was found that the maximum coupling between the two antennas results in a power level at the input of the DTV receiver in the range of -2 to -10 dBm depending on the gain of the receiving antenna.

• When the transmit antenna is turned vertically, the cross-polar coupling between the two antennas results in a power level at the input of the DTV receiver of -26 dBm to -32 dBm exceeded for 1% of the antenna orientation combinations except for the SquareShooter at the lower and upper edges of the frequency range due to its circular polarization design.

• The tolerance for the receive antenna polarization tilt angle can be +/-10 deg. before the coupling between the two antennas starts to increase significantly. Tighter tolerance would result in better on-axis cross-polar discrimination but this is masked by the poor antenna polarization purity in off-axis directions.

Conclusions (Cont’d)

• If -26 dBm is used as the reference level for the signal coupling from a 4 Watt WRAN CPE into a DTV receiver, this mean that the alternate channel interference from the nearby CPE can be kept 18 dB below the -8 dBm accepted saturation level of the DTV receivers.

• Since the alternate channel signal level reaching the DTV receiver is -26 dBm and that a 1 dB desensitization is the limit for out-of-band emission from the CPE, the relative out-of-band rejection at the output of the CPE can be calculated as follows:

– Acceptable out-of-band energy at the input of the DTV receiver:

POBO = -83.9 dBm -15.2 dB - 5.9 dB

= -105 dBm

– Relative out-of-band rejection at the output of the WRAN CPE:

Rejection = -26 dBm - 105 dBm

= 79 dB

• The -26 dBm DTV receiver input power which corresponds to 4 Watt EIRP should be used as the reference level to calculate the EIRP profile for closer-in channels and image frequency interference once the required D/U ratios are known.
