Comparison of Expected Performance on B3G Spread Spectrum Mobile Radio Links at 1.9 and 5.8GHz Based on Propagation Measurements

摘要

For planning purposes, there is a need for the evaluation of expected performance on mobile radio links in anticipated new frequency bands and comparison of results with 2GHz band performance estimates evaluated by the same methods. To that end, this paper reports the application of a semi-analytical technique to estimate average binary phase shift keyed direct sequence spread spectrum mobile link error rates at 1.9 and 5.8GHz from time series of channel response estimates derived from data recorded during propagation experiments with a 5 mchps pseudo-noise channel sounder. This work is unique, as the methods used incorporate the consideration of self interference as well as random channel variations based on direct analysis of the experimentally-determined channel response estimates, rather than simplified models for either the self interference or the channel variations.
