摘要： A signal selection system is disclosed wherein a plurality of received signals are analyzed to determine their statistical characteristics. These characteristics are compared to a predetermined statistical distribution. The signal that is statistically closest to the statistical characteristics of a known signal is selected for further processing and reception.

摘要： A data detector is disclosed wherein a received signal is analyzed to determine its statistical characteristics. These characteristics are compared to a predetermined statistical distribution. If the signal is statistically close to the statistical characteristics of a known signal a detect signal is generated and the received signal is passed for further processing and reception.

摘要： In a mobile communications system, a plurality of base stations may receive the same signal, whereby the "best" reception may be determined. The plurality of received digital signals are combined to form a majority signal. Each of the received digital signals is compared to the majority signal to estimate the bit-error-rate (BER) of each received signal. If the difference between the highest and lowest BER is less than a predetermined threshold, the majority signal is selected for reception. Conversely, if the BER difference is greater than the predetermined threshold, the received digital signal with the lowest BER is selected for reception. Thus, the signal with the lowest BER is selected to provide the best possible communications.
