摘      要：An efficient reduced search trellis decoding algorithm in which the decoder selects a part of existing paths by using a threshold value of the path metric is proposed. The threshold value at each time stage of the trellis is found by simply investigating the statistics of the path metrics, and does not require any prior knowledge such as the signal-to-noise ratio.
