An experimental transmission system at 8mm-wave was built up to perform a multi-channel transmission of audio and video signals in frequency reuse, due to space separation and polarization isolation. The features of such an 8mm-wave communication systems is described in details with respect to system construction and performance. Based on carrier-to- noise ratio and the signal level available, the attenuation margin and link availability are evaluated in terms of path length and specific rainfall distribution at Hong Kong. The quality of the demodulated video and audio signals is used for the analysis of co-channel interference and multipath effects. The experiment results show that the polarization isolation is more than 18.5dB, space isolation is more than 24.1dB, and a good quality in transmission of TV programs is observed in frequency reuse situation under a uncritical condition. Finally, a simplified scheme of the application of this system in wharf container dispatching and management is proposed.
