Abstract

This paper presents the implementation of a multiple antenna communication system using low-density parity-check (LDPC) codes on the software-defined radio (SDR) platform developed at EPFL´s Mobile Communications Laboratory. After briefly presenting the general structure and the main capabilities of our SR platform, we describe the methods and algorithms used for designing, encoding and decoding the LDPC codes for MIMO (multiple input multiple output) systems. We have implemented MIMO LDPC systems with up to four transmit and four receive antennas and performed on-the-air measurements which show strong agreement with the theory.
