Abstract :
A universal baseband signal processing system for I/Q modem based on DSP and ASSP (application specific standard product) is proposed in this paper. By choosing an universal digital radio baseband processor (ASSP) as the co-processor of DSP, the computation burden on DSP has been released significantly. Compared with some traditional solutions to the issue, the technique discussed in this paper is more promising and attractive. It is extremely compact and power-efficient that is often required by the portable devices in mobile communication. While in the illustration of the system, special emphases are laid on the architecture and operation principle of the system and the algorithms used in the baseband signal processing.
