Abstract This paper presents an overview of data receivers for the GSM system. First, the various phases of receiver evolution are identified. Next, the modulation format, the propagation channels and the system characteristics that have direct impact on the receiver design are outlined. Important design considerations and possible tradeoffs are identified, followed by a discussion of equalization techniques and a comparison of their performance. Implementation issues are also covered, in particular the tradeoff between flexibility and power consumption. We conclude by addressing recent advanced data receiver developments such as EDGE, blind equalization, multiuser (joint) detection and adaptive antenna arrays.
Key words: Mobile communications, GSM, modulation format, propagation channels, equalization techniques.
