Recently, wireless communication has turned into a very fast-growing market. GSM [2] gives a good example with a total number of 135 million users world-wide by the end of 1998, of which 65 million new customers subscribed in the last year. This impressive growth is based on the underlying technologies. The latter are the topic of this part: the study of complex communication functionality and related algorithms as well as their realization in hardware and software.
Digital Signal Processors (DSPs) are a key component for implementing communication algorithms. Very often, we encounter embedded DSP cores where the DSP is integrated on a silicon chip together with a controller core, memories, hardware accelerators, and dedicated periphery blocks. For many algorithms, the DSP represents the essential block in the implementation, e.g. voice codecs, channel equalizers, error correction, encryption, interference suppression, multi-channel and multi-beam reception as well as additional features like voice recognition. DSP performance is often measured in terms of...
