ANTENNA SWITCHED DIVERSITY RECEIVER

摘要

The present invention discloses an antenna switched diversity receiver comprising a plurality of physically separated antennas, a switching unit for selectively switching to one of the plurality of antennas to receive a burst in a time series, a decoding unit for decoding transmission data contained in the received burst in a reversed manner to coding, a bit-error-detecting unit for detecting a bit error in decoded data in each received burst, and a control unit for controlling the switching unit in accordance with the bit-error detection result. The receiver may additionally include a RSSI checking unit for checking a RSSI of a switched antenna and a RSSI holding unit for holding a RSSI. The receiver constructed as above controls switching based on a bit error in each burst alone or together with the RSSI. As a result, the receiver obtains excellent diversity effect while being compact and economical.
