Abstract :
Frequency offset can introduce considerable difficulties in both the training and detection of an equaliser based system. In the ETSI HIPERLAN (HIgh PErformance Radio LAN) standard, the oscillators are specified to be within 10 ppm. Obviously, the residual frequency offset in the received baseband signal can seriously affect the final performance of the system. We present the design of suitable frequency offset correction and synchronisation codes. These codes are then applied to a CMF (channel matched filter) structure which is followed by a low complexity DFE implementation based on the zero forcing algorithm. The performance of such a receiver is analysed for the HIPERLAN scenario and then compared with that obtained from a DFE using the LMS algorithm
