Wireless Personal Area Networks are increasingly widespread In their application. These range from simple remote controls to highly complex networks that allow the communication of heterogeneous data-collecting devices and actor devices via routing nodes and gateways, to networks such as wired JP networks. Key performance aspects for wireless personal area networks are the large number of nodes capable of working within the same reception area and the energy consumption of such nodes. This work shows how equalisation for wireless personal area networks can be realised with a small increase in hardware, in order to achieve performance improvements in highly dispersive environments. The proposed ideas are extended to a multiple-antenna solution which can be made downwards-compatible to the appropriate IEEE standard. In this manner, the performance in terms of either bit rate or robustness can be improved. For both equalisation and multiple-antenna procedures it is shown how the existing pre-amble can be used to find an estimate of the channel impulse response. This processing is performed in the time domain. Equalisation as well as multi-antenna channel separation is achieved by one set of cyclic filters operating at the chip rate. This allows a simple hardware design for integration. Selected methods are tested in real-time in a testbed for wireless personal area networks and.are shown to offer real performance improvements.
