Title: Diversity receiver
Inventor: SAWAMURA HIROSHI
IPC: H04B1/10
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a sufficient diversity effect even when an antenna input is low by eliminating noise that is detected from an signal output an antenna receives by a squelching means and outputting it. SOLUTION: An antenna input of an antenna 1a goes through a BPF 2a and becomes a signal only in a receiving band, and a limitter amplifier 3a outputs an amplitude constant signal. An envelope detection circuit 6a omits a small input part and outputs a signal voltage corresponding to an antenna input as a 1st size signal. A noise squelch circuit 11a outputs a signal that corresponds to the ratio of thermal noise to an antenna input level. An adder 12a subtracts an output of the circuit 11a from an output of the circuit 6a and acquires reliability information Ri that is in proportion to an antenna input level. It similarly acquires a 2nd series of reliability information Rj. With this, a maximum likelihood series deciding part 9 surely decides what is the surest in transmission phase deviation and realizes high quality communication.
