POLARIZED WAVE DIVERSITY TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a polarized wave diversity transmission system for obtaining large fading improvement effect in a mobile communication, etc. SOLUTION: A transmitter 1 sends a radio wave which is circular polarized wave or 45 deg. or 135 deg. polarized wave from an antenna 2. The radio wave is made incident on vertical and horizontal receiving antennas 4 and 5 and orthogonal polarized components are received, respectively. Their receive signals are supplied to receivers 6 and 7 and a diversity receiving circuit 8 selects one of the outputs of the receivers or puts them together, so that a reception output circuit 9 obtains the output of the polarized wave diversity reception.
