Low-Complexity Non-Binary LDPC and Modulation Schemes communicating over MIMO Channels
Low-Complexity Non-Binary LDPC and Modulation Schemes communicating over MIMO Channels
In this contribution, Pearl’s belief propagation (BP) algorithm is invoked for constructing a belief network, which is employed for developing a joint detection aided transmit diversity scheme and a non-binary LDPC decoder constructed over a finite field of GF(q). An exciting bit-by-bit detection scheme is further developed for creating the joint purly symbol-based LDPC/transmit diversity decoder. The performance of the proposed symbol-based system is benchmarked against the original bit-by-bit detection scheme, when communicating over an uncorrelated Rayleigh fading channel using two transmitters and two receivers. The associated detection complexities are also compared.

Abstract
In this contribution, Pearl’s belief propagation (BP) algorithm is invoked for constructing a belief network, which is employed for developing a joint detection aided transmit diversity scheme and a non-binary LDPC decoder constructed over a finite field of GF(q). An exciting bit-by-bit detection scheme is further developed for creating the joint purly symbol-based LDPC/transmit diversity decoder. The performance of the proposed symbol-based system is benchmarked against the original bit-by-bit detection scheme, when communicating over an uncorrelated Rayleigh fading channel using two transmitters and two receivers. The associated detection complexities are also compared.
