Abstract

Portable terminals supporting the Digital Enhanced Cordless Telecommunications (DECT) standard have entered the world market in the last few years. For such devices low energy dissipation is of critical importance. In this paper, the design of a low-power fully digital baseband receiver that embodies innovative and conventional low-power optimizations is presented. The proposed baseband receiver complies with the DECT standard as far as digital modem functions are concerned. The developed energy-conscious, low complexity DECT demodulation algorithm and the low-power hardware architecture are described in a detailed manner
