Future Wireless

Orthgonal Frequency Division Multiplexing (OFDM) is core to emerging and future wireless systems. Of note, 802.16, 802.20 and 3GPP LTE all depend upon OFDM. The goal of this project is to generate core expertise in this area, publish in leading conferences and journals while securing valuable IP for the project participants. Numerous ASIC prototypes will result.

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.

LDPC Codes

Low-density parity-check codes are a class of iterative error correction codes with capacity-approaching decoding performances. This project investigates the design and decoding of low-density parity-check codes and a related class of codes called repeat-accumulate codes.

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.
