A Class of Trellis-Codes for Partial Response Channel

概要
- 論文の詳細を見る
We present a new class of trellis-codes for partial-response channel. Our code configuration is based on the coded 1-D scheme due to Wolf and Ungerboeck. However, no precoder between a convolutional encoder and the partial-response channel is used. A new lower bound on the minimum free squared Euclidean distance of channel code is shown. The bound is available for any PR channel with a finite response. New codes for 1-D and (1-D)(1+D)^2 channels are found by computer code search using the lower bound. Some of the new codes have excellent properties: a significant d^2_<free> and a small decoding complexity.
