Low complexity synchronisation, equalisation and diversity combining for home-based Hiperlan/1 transceivers

This paper discusses the development of a Hiperlan/1 radio modem for the simultaneous transmission of video, voice and data in the home environment. In particular, the performance of the wireless modem has been optimised to support MPEG II video streams. The modem will eventually be integrated with digital set-top box equipment to support wireless Internet and digital television applications around the home. This paper describes a number of enhanced architectures and algorithms that enable an efficient FPGA implementation of the baseband digital equaliser, synchroniser and diversity combiner. Results show that the entire baseband receiver can easily fit within a single Xilinx Virtex device and that error-free packet rates in excess of 99% are possible, even in worst case radio channels
