Optimal constellation design is important in military digital communications for Quadrature Amplitude Modulation (QAM). Optimization realizes a reduced probability of bit error (P...
— A signal space diversity (SSD) scheme is one of techniques to achieve diversity gain in fading channels. This method consists of two key operations: constellation rotation and ...
Abstract—It is well known that the Viterbi and Viterbi MonomialBased Phase Estimator, which includes the Mth Power Estimator, performs poorly for cross QAM signals. However, it i...
Abstract—This paper presents new low-complexity lattice-decoding algorithms for noncoherent block detection of quadrature amplitude modulation (QAM) and pulse amplitude modulatio...
