Abstract

This paper describes a method of evaluating transmission performance of parallel transmission in multipath propagation environments. Delay profiles measured in metropolitan Tokyo at a microwave frequency were used to obtain radio channel impulse responses, and the characteristic function method was used to efficiently estimate transmission performance under the assumption that the impulse responses have uniform distribution phases. Results show that the performance to be obtained by applying the parallel transmission technique is 100 times better than that of bare transmission in an example of a source data rate of 10 Mb/s
