Structured set partitions for high-order partial response channels

摘要

Multilevel modulation codes for partial response (PR) channels canbe constructed using a structured set partition (SSP) of channel outputwords, and a set of block codes with different error correctingcapabilities. We present SSP for the classical and modifiedE2PR4 channels. The coding gain 3.5 dB can be achieved at thelinear density 2.8 for ME2PR channel with the target[5,4,-3,-4,-2] given by Sawaguchi et al. (see Proc. GLOBCOM-98, 1998)
