Abstract: A signal processing method and an apparatus thereof. A first signal is received, wherein the first signal includes x symbols. N types of quantization levels are determined based on a signal distribution parameter of the first signal. A second signal is determined based on the first signal. Quantization processing is performed on the second signal to obtain x groups of first quantization results, wherein the x symbols are in one-to-one correspondence with the x groups of first quantization results. The x groups of first quantization results are mapped to a quantized first signal, wherein the quantized first signal includes x quantization levels, and each group of first quantization results is mapped to one of the N types of quantization levels. Signal processing is performed on the quantized first signal.
