The authors present the results of field experiments on 920 MHz band high-speed digital signal transmission in the Tokyo metropolitan area. The average bit error rate (BER) performance of minimum-shift keying (MSK) in multipath fading channel is shown, with the estimated BER performance introduced by using a two-path model. The effect of antenna pattern diversity is also shown for 128 kb/s MSK signaling. The results show that time delay spread has a very bad effect on a digital signal transmission system with a bit rate of more than 64 kb/s. The antenna pattern diversity is considered to be one of the corrective techniques for such high-speed digital signal transmissions.
