Common use of Combining diversity Clause in Contracts

Combining diversity. In ITS configurations with 2 or more TMUs per sector, the system is configured to execute two-path maximum ratio combining in the uplink. The implementation of this feature delivers the theoretical benefit of maximum ratio combining with less than 1 dB implementation loss. The TMU receiver is wideband and covers all of the uplink spectrum. This means that the IF signals from 2 TMUs in the same sector differ only by virtue of being received from 2 physically separated antennas. The two I.F signals are fed to separate arms of each receiver pair of every TBM in the sector. The TBM hosts three such receiver pairs where each pair is configured to an appropriate channel. The maximum ratio combining algorithm is executed independently on each receiver pair.
