DECT is a cordless telephone standard whose applications are broadening with the

advent of PCS services, wireless local loop (WLL), and the increasing demand for

high data-rate wireless local area networks (WLANs).

This thesis investigates the performance of DECT in different channel conditions.

DECT is simulated using the Signal Processing WorkSystem (SPW) software in

different channels including the additive white Gaussian noise (AWGN) channel,

the flat faded Rayleigh channel, the frequency selective faded Rayleigh channel,

and the Ricean channel. The effect of cochannel and adjacent channel

interference is also investigated.

In order to quantify the RF channel dispersive properties, and other parameters

that determine performance in a radio channel, channel impulse response

measurements at 1.9 GHz are made. Parameters that help describe the radio

channel are identified and calculated from the recorded power delay profile


Finally, a mean-opinion-score (MOS) rating was performed for National

Semiconductor Corporation's implementation of DECT in the indoor, indoor-to-

outdoor, and outdoor environments. A comparison is made between the MOS and

propagation measurements. It is found that the performance of DECT is very

closely related to the RMS delay spread and the path loss in the RF channel.
