A hierarchy of receiver options for DECT systems

The DECT system is targeted at a large range of different applications, which have widely differing radio conditions. These can vary from short range line of sight indoor systems to relatively hostile outdoor environments. The authors present and discuss a range of matching options for the radio receiver, with particular emphasis on possible structures for space diversity operation and various options for equalisation. Illustrations of performance obtained by both software simulation and hardware testing are included. It is concluded that the DECT standard allows manufacturers to make technology choices suitable to the applications of interest. This includes even demanding outdoor environments where advanced processing can be used to obtain robust performance with relatively low complexity
