Two new signal space detectors designed to take advantage of maximum transition run (MTR) coded modulation are presented. These detectors are designed to perform across a wide range of densities and offer lower error rates than a 3D-110 detector at low densities while requiring only modest increases in complexity. The first scheme, 2D-121α employs an equalization constraint that reduces low density noise correlation relative to the 3D-110 target. The second uses a 3D-110 detector but includes a linear noise predictive filter to reduce the effective noise between the minimum distance sequences. Analysis and simulation results indicate that the two detectors perform equally well in terms of bit error rate
