This paper is concerned with the design and performance of nonbinary LDPC-coded differential modulation systems. A low-complexity joint detection/decoding method for noncoherent demodulation is proposed, in which the hard-messagepassing strategy is used for a joint factor graph. It combines trellis-based differential detection aided with channel prediction and the reliability-based decoding of nonbinary LDPC codes introduced in [1]. The Max-Log-MAP algorithm with soft-in hard-out is used for the differential detection. Simulation results show that the proposed method can offer good performances with a greatly reduced complexity.

The work presented in this paper aims to establish whether a combination of the Logarithm of Likelihood Ratio (LLR), Turbo Codes and Modulation Schemes enhances high and efficient performance in communication systems by minimizing transmission error rates for any given bit combination. Performance Analysis and Interpolation of Turbo codes over Additive White Gaussian Noise and Rayleigh Fading Channels will be explored. This highly combinatorial technique should influence optimum performance in Broadband communication systems. Computed results are presented for various parameters employed in the formulations outlined throughout this paper.

“…Most works investigated the design of the noncoherent receiver, such as multiple-symbol differential detector. In [11] and [12], the system comprising the cascade of channel codes (such as turbo codes), an interleaver and a differential encoder was investigated. In [1], spectral-efficient noncoherent QAM was studied for the channel with an unknown complex channel coefficient.…”

In this paper, we investigate block-coded QAM constructed by multilevel coding for the noncoherent generalized likelihood ratio test (GLRT) detector. For the AWGN channel, we derive a new GLRT detector and the corresponding distance. The minimum noncoherent distance of block-coded QAM is derived and two construction of noncoherent block-coded QAM (NBC-QAM) are proposed accordingly. In the NBC-QAM scheme, the error performance can be optimized by adjusting the constellation. The superior error performances of NBC-QAM are verified by simulation results.
