Description

technical field

[0001] The present invention relates to an antenna switching receiving system for switching antennas to perform reception in a wireless communication system. Background technique

[0002] In a wireless communication system, level degradation due to multipath fading (Multipath Fading) is cited as one of the issues. The signal received by the receiving antenna is not only a signal directly input from the transmitting antenna to the receiving antenna, but also a signal input via a plurality of different paths. Therefore, signals (multipaths) having different delay times are also input to the receiving antenna, so that the signals overlap each other, cancel each other, etc. at the receiving antenna end to cause the reception level to deteriorate. This is a phenomenon called level degradation caused by multipath fading.

[0003] As a typical countermeasure for avoiding the influence of the level degradation caused by the multipath fading, there is a multi-carrie...
