Abstract Efficient quantizer design is vital in high‐speed optical receivers. In this paper, the authors propose a three‐level (1.5‐bit) reliability‐based quantizer for low‐complexity soft decoding of low‐density parity‐check (LDPC) cod

Abstract In this study, the target detection and signal design problems in the presence of signal‐dependent interference for a colocated multiple‐input multiple‐output (MIMO) radar employing a space‐(slow) time transmit signal are addressed.

Abstract We propose a method to substantially reduce the computational complexity of iterative decoders of low-density parity-check (LDPC) codes which are based on the weighted bit-flipping (WBF) algorithm. In this method, the WBF-based decoders are

The adaptive radar detection of a point target in the presence of signal-dependent interference, also known as system-dependent clutter, is addressed in this paper. Here, the radar signal is assumed to be an intra-pulse modulated waveform and the tar

This paper presents a new low complexity sphere decoding (SD) for the generalized spatial modulation (GSM). We introduce a pre-processing stage using the lattice reduction (LR) aided minimum mean squared error (MMSE) equalization in the GSM systems.
