Abstract
A dynamic capacity allocation spread spectrum CDMA communications system for overlaying, at least in part, geographically and in frequency a radio-relay system. A first receiver, located near the relay receiver of the radio-relay system, measures a first power level within the relay bandwidth of the radio-relay system. A second receiver, located near the relay receiver, measures a second power level outside the relay bandwidth of the radio-relay system. The first power level is compared to a predetermined threshold. A ratio signal is generated from the first power level and the second power level. When the first power level exceeds the predetermined threshold, the ratio signal is used to regulate the power level and dynamically allocate the capacity transmitted from each spread-spectrum-base station.
