发明名称 IMPAIRMENT DETERMINATION FOR A DIVERSITY ANTENNA SELECTION PROCESS
摘要 A diversity selection process which tests to determine whether poor reception is caused by co-channel interference or multipath fading is disclosed. The impairment is determined by first testing the quality over several frames. Unless the quality is poor over these several frames, the system tests for multipath fading by selecting the antenna with the greater signal strength, provided no hold condition exists. However, if poor quality has been present over the several frame period, the system selects the other antenna if its RSSI is greater. However, the system also tests the RSSI received on the current antenna and determines the impairment was co-channel interference if the signal of quality was sufficiently high. In which case a hold condition is set for a number of frames to prevent excessive switching.
