Broadband wireless communication systems requires that systems be designed to operate with high spectral efficiency in wideband channels. Such requirements make OFDM an attractive transmission technology due to the fact it exploits the computational efficiency associated with frequency domain equalisation. This has lead to the analysis of the applicability of such techniques to existing systems . In particular, the 3GPP-UMTS system, where HSDPA offers a significant increase in performance by using multi-code W-CDMA transmission, is considered herein. This paper proposes a computationally efficient solution that performs equalisation and despreading using frequency domain processing, enabling the same equaliser to be used for both OFDM and W-CDMA. The solution is thus particularly applicable to devices that support fixed-mobile convergence where multi-mode support of these two transmission techniques is likely to be required. A complexity analysis is included and performance is verified though simulation.
