Abstract

The class of minimum shift keyed (MSK) and RC modulation schemes provides several properties useful in mobile radio, e.g. spectral efficiency, constant envelope, and moderate complexity. In order to profit from multipath reception, a data rate of 525 kHz, resulting in moderate bandwidth, is chosen. For the mobile radio channels, appropriate Gaussian wide sense stationary uncorrelated scattering (GWSSUS) models are assumed and a software simulator for those channels is described. An improved method for calculating the channel parameters is proposed. Based on the GWSSUS model, bit error rates (BERs) of MSK and RC modulation schemes in time- and frequency-selective mobile radio channels are measured and compared with computed data
