MIMO Soft Demodulation via Semidefinite Relaxation: Efficient Dual-Scaling Implementation and Performance Analysis
Abstract
For MIMO systems with binary or QPSK signalling, soft demodulation techniques based on semidefinite relaxation (SDR) offer a desirable balance between performance and computational cost. In this paper we expand on an extension of that approach to systems with higher-order QAM signalling. In particular, we develop a customized dual-scaling algorithm to solve the semidefinite program that constitutes the core computational task of the …
