Sparse code multiple access (SCMA) is a non-orthogonal multiple access scheme. This scheme allows to increase the number of active users inside a given time-frequency resource. The paper considers the spectral efficiency of coded uplink SCMA system i

Fifth generation wireless communication systems should support, among other things, very large number of simultaneous connections. To address this requirement, various schemes of non-orthogonal multiple access (NOMA) were proposed that allow to incre

A method of codebook optimization for noncoherent transmission over fast fading channel is presented. Noncoherent reception is considered in a wide sense when the instantaneous channel state information (CSI) is not available, but statistical propert

A reception method is proposed to improve error rate performance of quadrature amplitude modulation (QAM) signals transmitted over fast fading channels. The method can be treated as a simplified version of generalized likelihood ratio test (GLRT). In

Two methods are proposed to improve error rate performance for reception of short packets with quadrature amplitude modulation (QAM). Both approaches are based on the same idea as generalized likelihood ratio test (GLRT) but have reduced computationa

The problem of joint optimization of coding and modulation for noncoherent communications is considered. To minimize block error rate, an autoencoder network is used. The network architecture is designed to mimic the end-to-end operation of a communi
