Abstract
An optimal digital signal combining algorithm for arraying is proposed. Our approach is a blind combining technique, which doesn’t require any training sequence. In achieving coherence among various receivers, the combining algorithm attempts to maximize the combined output signal-to-noise ratio (SNR). It’s shown in numerical simulations that the combining loss of an 8-element array could limited to about 0.7dB at 2000 symbols /interval in low SNR ,which is about 2.5dB combining loss less than the traditional MMSE adaptive weight estimation using a single reference signal. This results suggests that the combining algorithm proposed here is capable of improving the combining SNR without complex computation.
