A receiving apparatus for a random access channel of a CDMA mobile communication system |
摘要 |
A random access channel receiver used in a base station of a CDMA mobile communication system is provided. The receiver is only provided with a single signal decoding part for performing burst reception of control request signals having different off-set timing each other. A synchronizing circuit calculates correlation value at each off-set timing, and a synchronism determining and establishing circuit determines the off-set timing to be used for a synchronizing signal for receiving the signal frame currently arriving by monitoring correlation values of respective off-set timings, and alters the off-set timing for the synchronizing signal to better quality of signal if a plurality of signal frames of different off-set timing are arrived. The signal frame of less quality is discarded, or abandoned its decoding processing. <IMAGE> |
