Abstract: In a basestation, both chip and symbol rate processing are performed within the same DSP. The tasks involved in these baseband processing operations are performed using functions selected from groups of functions available for performing certain tasks. For example, demodulation can be performed using either a rake receiver function or an adaptive equalisation function, the choice being made according to the prevailing circumstances, for example, on the basis of such factors as available baseband processing power, delay spread and spreading factor.
