Method and apparatus for selecting a digital signal from a plurality of digital signals

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.
