摘要：

One-bit error-feedback quantizers for uniform linear antenna arrays are developed to enable efficient spatial noise shaping. The SNR of the maximum ratio combiner for received signals quantized by one-bit error-feedback quantizers is evaluated. Then, the optimal error-feedback quantizer that maximizes the worst SNR for the signals whose arrival angles are in a fixed range of interest is designed. Numerical results are provided to show that our one-bit spatial noise shaping exhibits flat BER performance for the signals from the prescribed range.
