    摘要: Simplified methods of searching a codebook table are provided. These methods perform a codebook search for a plurality of pulses, one pulse at a time, in order of increasing to decreasing pulse significance, wherein pulse significance is defined as the relative contribution a given pulse provides to minimizing the mean-squared error between the source signal and the quantized sequence of pulses.
