Abstract

Digital signal processing is a key technology for the expansion of mobile communications and more and more functions in mobile units and base stations are performed digitally. The evolution concerning two major functions is reviewed, namely A/D conversion using an integrated band-pass high performance sigma-delta modulator and adaptive channel equalisation/estimation for optimum detection. Then, antenna array processing techniques are discussed, in view of the potential they have in the context of space division multiple access (SDMA), to improve the efficiency of cellular networks
