Symbol Interleaved Parallel Concatenated Trellis Coded Modulation
نویسندگان
چکیده
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 memory elements in a single row. Simulation results show that performance is as close as 0.5 d B to constrained capacity.

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 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 کاملParallel concatenated turbo codes for continuous phase modulation
There are several ways to use iterative decoding techniques with coded continuous phase modulation (CPM). This paper presents a method using parallel concatenation of convolutionally-coded CPM. All CPM schemes can be decomposed into a ring convolutional code and a memoryless signal mapper. This allows a properly designed convolutional code trellis to be combined with the CPM trellis, producing ...
متن کاملNear-Capacity Turbo Trellis Coded Modulation Design Based on EXIT Charts and Union Bounds
Bandwidth efficient parallel-concatenated Turbo Trellis Coded Modulation (TTCM) schemes were designed for communicating over uncorrelated Rayleigh fading channels. A symbol-based union bound was derived for analysing the error floor of the proposed TTCM schemes. A pair of In-phase (I) and Quadrature-phase (Q) interleavers were employed for interleaving the I and Q components of the TTCM coded s...
متن کاملStaggered Trellis Coded Modulation
A special construction method for parallel concatenated trellis coded modulation, namely staggered trellis coded modulation, is presented. This coding scheme is similar to that of the recently introduced binary laminated turbo codes and it comprises a convolutional structure due to an additional block-wise memory. The encoder and a possible decoder for this new code construction is presented an...
