Abstract:
1. A method comprising: receiving an RF signal, said received RF signal comprising a plurality of information channel signals each comprising different code division multiple access data spread using a different spreading code, wherein each of said plurality of information channel signals are transmitted in one of a plurality of transmission bands, and each of said plurality of information channel signals is carried on one of a plurality of carrier frequencies; down-converting said received RF signal by a single down-converter to form an intermediate signal, wherein said single down-converter is arranged to receive said received RF signal and simultaneously multiply said RF signal by a plurality of oscillator signals when operating in a first mode and multiply said RF signal by a single oscillator signal when operating in a second mode, wherein said intermediate signal comprises down-converted versions formed by the single down-converter of each of said plurality of information channel signals, and said down-converted versions of each of said plurality of information channel signals are generated from a plurality of frequencies, said down-converted versions of each of said plurality of information channel signals are within a common frequency spectrum; processing the intermediate signal in a baseband stage to generate a baseband signal; and decoding said baseband signal to extract data from said down-converted versions of each of said plurality of information channel signals.
