Baseband signal switching arrangement for diversity reception in a PCM radio communication system

摘要

A baseband signal switching arrangement for diversity reception in a PCM communication system is disclosed. The switching arrangement is characterized by the provision of a 1/n write-in frequency-dividing counter in each receiving channel to count clock signals in response to being reset by a frame signal and n buffer memory circuits for successively writing bit information of a received digital signal in response to the n frequency-divided outputs of the 1/n frequency-dividing counter. The switching arrangement further includes a 1/n read-out frequency-dividing counter which is adapted to successively read out memory outputs of one set of the n buffer memory circuits and a switching means for enabling the 1/n read-out frequency-dividing counter to selectively read out memory outputs of a given set of buffer memory circuits.
