Abstract: We review the principle of multidimensional (multi-D) trellis coded modulation (TCM). We describe the structure of multi-D TCM schemes and discuss their ...

Abstract: We investigate the association between constellation shaping and bit-interleaved coded modulation with iterative decoding (BICM-ID). To this end, we consider a technique which consists of ...

skip = gr.skiphead(gr.sizeof_float, L) # skip the first L samples since you know they are coming from the L zero symbols #metrics = ...

Communication-system designers have always had to deal with trade-offs among data reliability, efficient use of available spectrum, data throughput, and cost. Error-correction coding (ECC) is one of ...
