Abstract
A communications method uses simultaneously at least two receivers to reduce a need for data retransmissions. When using multiple receivers it is enough that at least one of the receivers outputs a correct bit set which are preferably checked by Cyclic Redundancy Check (CRC). The method comprises the following to be performed in a radio modem: a) receiving the same sample of a signal in a first receiver and in a second receiver; and in response to the same sample b) obtaining a first bit set from the first receiver and a second bit set from the second receiver; and c) determining whether the first bit set or the second bit set is a correct bit set. A retransmission request is sent only when the first and second bit sets are erroneous. This reduces latencies in the transmission. One can change receivers depending on the radio frequency (RF) circumstances.
