Multidimensional trellis coded phase modulation using a multilevel concatenation approach .II. Codes for the AWGN and fading channels
نویسندگان
چکیده
-In this paper, we will use the construction technique proposed in [1] to construct multidimensional trellis coded modulation (TCM) codes for both the additive white Gaussian noise (AWGN) and the fading channels. Analytical performance bounds and simulation results show that these codes perform very well and achieve significant coding gains over uncoded reference modulation systems. In addition, the proposed technique can be used to construct codes which have a performance/decoding complexity advantage over the codes listed in literature.

Multidimensional trellis coded phase modulation using a multilevel concatenation approach. I. Code design
-The first part of this paper presents a simple and systematic technique for constructing multidimensional M-ary phase shift keying (MPSK) trellis coded modulation (TCM) codes. The construction is based on a multilevel concatenation approach, in which binary convohitionai codes with good free branch distances are used as the outer codes and block MPSK modulation codes are used as the inner code...
متن کاملTrellis-Coded Quadrature Amplitude Modulation with 2N-Dimensional Constellations for Mobile Radio Channels
– Using a modified Wei method, originally designed for AWGN channels, we have constructed fourand six-dimensional trellis codes with rectangular signal constellations for frequency-nonselective mobile radio channels. Applying a novel way of partitioning the 2-D constituent constellations, both into subsets with enlarged minimum Euclidean distance and subrings including equal energy signal point...
متن کاملTurbo Trellis Coded Modulation with Iterative Decoding for Mobile Satellite Communications
In this paper, analytical bounds on the performance of parallel concatenation of two codes, known as turbo codes, and serial concatenation of two codes over fading channels are obtained. Based on this analysis, design criteria for the selection of component trellis codes for MPSK modulation, and a suitable bit-by-bit iterative decoding structure are proposed. Examples are given for throughput o...
متن کاملTurbo Trellis Coded Modulation on Partially Coherent Fading Channels
| In this paper, we design parallel concatenated convolutional codes (PCCCs) for trellis coded modulation (TCM) over the following discrete two-dimensional (2D) channels: (a) a slow-fading Rayleigh channel with discrete carrier tracking by a phase locked loop (PLL), where the PLL signal-to-noise ratio (SNR) is proportional to the fading amplitude squared; (b) an additive white Gaussian noise (A...
متن کاملPerformance of Hybrid Concatenated Trellis Codes CPFSK with Iterative Decoding over Fading Channels
Concatenation is a method of building long codes out of shorter ones, it attempts to meet the problem of decoding complexity by breaking the required computation into manageable segments. Concatenated Continuous Phase Frequency Shift Keying (CPFSK) facilitates powerful error correction. CPFSK also has the advantage of being bandwidth efficient and compatible with non-linear amplifiers. Bandwidt...
