Signal space implementation of sampled-data receivers

Several of the basic algorithms to be used by general-purpose digital signal processors (DSPs) in recovering digitally modulated signals are discussed. DSP-based algorithms for data detection, carrier tracking, and symbol synchronization are presented from the vector space point of view. This allows for the development of general algorithms that are applicable to a wide range of modulation formats without the need for specialized processors. The result is a set of initial design rules, which can be used in the DSP implementation of multimode multirate modems. Only quadrature amplitude modulation (QAM)-type signaling formats are considered.<
