LDPC Codes

This project investigates the design and decoding of low-density parity-check (LDPC) codes and a related class of codes called repeat-accumulate (RA) codes. This project includes an online implementation of density evolution and offers resources related to LDPC and RA codes.

Lattice Reduction Aided MIMO Detection

Lattice-reduction-aided detection (LRAD) has been identified as a way of improving the performance of linear detection strategies imperative for low complexity MIMO detection.

MCMC MIMO Detection

Details Pending.

MCMC Multi-User Detection

The application of Metropolis-Hastings and Gibbs Sampling algorithms to CDMA Multi-User Detection. This approach offers near-maximum likelihood detection with soft-outputs. This project investigates the computational feasibility of this approach.

MIMO Communications Testbed

This is a hardware device designed to be used in the design and testing of wireless MIMO communications systems. It is connected to a PC via USB 2.0 or ethernet and uses an on-board FPGA to allow implementation of algorithms in logic, together with provision for multiple radio modules.
