We propose a method to form a non-uniform decision boundary (NUDB) for $M$ -ary quadrature amplitude modulation (MQAM) signals to reduce bit error floor (BEF) in the presence of phase error. We put our focus on angle distances between MQAM symbols an

A digital channelizer converts a received wideband signal into narrowband sub-channels in the digital domain to enable signal processing with reduced clock rate. Polyphase structure–based implementation is widely recognized as an efficient method f

While the performance analysis of linear zero-forcing (ZF) and minimum mean-square error (MMSE) receivers has received much attention, there has been no exact closed-form distribution of signal-to-interference-plus-noise ratio (SINR) for MMSE multipl

It is important to understand the properties of spatial correlation matrices in multiple-input multiple-output (MIMO) systems. In this paper, we derive new bounds for the maximum and minimum eigenvalues of spatial correlation matrices characterized b
