Turbo-encoder design for symbol-interleaved parallel concatenated trellis-coded modulation
This paper addresses turbo-encoder design for coding with high spectral efficiency using parallel concatenated trellis-coded modulation and symbol interleaving. The turbo-encoder design involves the constituent encoder design and the interleaver design. The constituent encoders are optimized for symbol-wise effective free distance, and each has an infinite symbol-wise impulse response. We ident...
متن کاملSymbol Interleaved Parallel Concatenated Trellis Coded Modulation
This paper presents a method for efficient coding at high spectral efficiency using parallel concatenated trellis coded modulation (PCTCM) with symhol interleaving. The constituent encoders are optimized for symholwise free distance, and each has an infinite symbol-wise impulse response. In many eases of practical interest, the optimal structure for these constituent encoders connects the memor...
متن کاملBit vs. symbol interleaving for parallel concatenated trellis coded modulation
This paper compares bit v.s. symbol interleaving for parallel-concatenated trellis-coded turbo codes, employing the turbo encoder structure proposed in [1]. To compare systems optimized with the same techniques, the paper extends the turboencoder design procedure proposed in [2] to bitinterleaved systems. We discuss a method to jointly design the multiple required interleavers for the bitinterl...
متن کاملMapping Rearrangement for Parallel Concatenated Trellis Coded Modulation
Mapping rearrangement (MaRe) for the hybrid ARQ (HARQ) based on the parallel concatenated trellis coded modulation (PCTCM) is analyzed. We demonstrate that the performance of the PCTCM receiver is intrinsically limited by the MaRe design and we propose a new mapping scheme to fit the structure of PCTCM transceivers. Depending on the HARQ scenarios, the proposed scheme offers gains between 0.1 a...
متن کاملParallel Concatenated Trellis Coded Modulation1
In this paper, we propose a new solution to parallel concatenation of trellis codes with multilevel amplitude/phase modulations and a suitable bit by bit iterative decoding structure. Examples are given for throughput 2 and 4 bits/sec/Hz with 8PSK, 16QAM, and 64QAM modulations. For parallel concatenated trellis codes in the examples, rate 2/3 and 4/5, 8, and 16-state binary convolutional codes ...
