Receiver and a communication assembly

Abstract

A receiver (70), suitable for use in a communication assembly configured to operate underwater, the receiver comprising, at least first one or more photodetectors (62a) and second one or more photodetectors (62b), wherein the first one or more photodetectors (62a) define a first detection area which can receive light, and the second one or more photodetectors (62b) define a second detection area which can receive light; at least a first multiplexer (74) which is configurable to selectively electrically connect any of the first one or more photodetectors (62a) or second one or more photodetectors (62b) to a signal detector module (66); a controller (75) which is connected to said least a first multiplexer (74) so that the controller (4) can selectively configure the first multiplexer (74) to electrically connect any of the first one or more photodetectors (62a) or second one or more photodetectors (62b) to the signal detector module (66); wherein, the controller (75) is configured to, configure the first multiplexer (74) to electrically connect the first one or more photodetectors (62a) to the signal detector module (66) and then determine a first quality factor which is which is representative of the quality of a signal output from the first one or more photodetectors (62a) to the signal detector module (66); and configure the first multiplexer (74) to electrically connect the second one or more photodetectors (62b) to the signal detector module (66) and then determine a second quality factor which is representative of the quality of a signal output from the second one or more photodetectors (62b) to the signal detector module (66); and compare the first quality factor and second quality factor to determine which signal output is better quality; and configure the first multiplexer (74) so that the first multiplexer (74) electrically connects whichever of the first one or more photodetectors (62a) or second one or more photodetectors (62b) provides said better quality signal output to the signal detector module (66). There is further provided a communication assembly which has the receiver (70).
