1. Joint Source-Channel Coding using Trellis Coded CPM
Sammanfattning : The thesis investigates Joint Source and Channel Coding(JSCC) using combined Trellis Coded Quantization (TCQ) and coded modulation. First we investigate a JSCC scheme using combined TCQ/Trellis Coded CPM (TCQ/TCCPM). Based on the BCJR algorithm for trellis coded CPM, we derive an optimal soft decoding algorithm for the considered systems. LÄS MER
2. Towards Fully Optimized BICM Transmissions
Sammanfattning : Bit-interleaved coded modulation (BICM) was introduced in 1992 as a new coded modulation (CM) scheme particularly well suited for fading channels and is nowadays considered the de facto CM scheme in wireless standards (HSPA, IEEE 802.11a/g/n, DVB-T2/S2/C2, etc.). LÄS MER

5. In-Line Bit Interleaved Serially Concatenated Coded Modulation
Sammanfattning : A communication system using in-line bit interleaved serially concatenated trellis coded modulation (SCTCM) over the additive white Gaussian noise (AWGN) channel is investigated. In-line bit interleaving refers to an interleaving method for which the random bit interleaver is divided into several independent constituent bit interleavers. LÄS MER
