Coded modulation by outright filtering

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceedingResearchpeer-review


We investigate the bandwidth and distance of codes created by ordinary lowpass filtering of a pulse stream. The encoder is thus a convolution, but over the reals. Performance of these codes is compared to the TCM and PRS code families; despite their simplicity, the new codes perform equally well. Since a simple decoder exists,
these are attractive codes.
