Adaptive sample rate converters (SRC) for the multi-standard mobile transceiver have been designed. GSM, UMTS and HIPERLAN2 standards have been chosen to establish the requirements for the SRCs. In the transmitter, the output signal of the data modulator is sampled at the symbol or chip frequency specified by the standards and needs to be converted into a common updating frequency of the D/A-converter. Pulse shaping and emission mask requirements are taken into account. In the receiver, A/D-conversion is also performed at a common fixed clock rate. Thus the SRC is needed to convert the A/D-converter sampling rate into a symbol or chip frequency that will be applied for further baseband signal processing. Channelization requirements defined by the standards are used as criteria for the performance analysis in the receiver. Based on the performance analysis, the complexity analysis is covered. It includes computational complexity, gate count, area and power consumption estimation for the chosen platform.
