Abstract:
1. A method comprising: receiving, at a wireless communication device, signals representing wireless data transmissions that are based on a message, the received signals including one or more previous signals and a current signal, wherein decoding of the message based on the one or more previous signals failed to successfully resolve the message, and wherein the current signal was transmitted in response to the one or more previous signals failing to successfully resolve the message; combining the received signals based on unequal weights to produce a combined signal, the weights include a first weight value assigned to the one or more previous signals and a second, greater weight value assigned to the current signal, the second weight value being based on a noise variance, the first weight value being based on a modified version of the noise variance, the modified version reflecting one or more decoding failures; and decoding the combined signal to resolve the message.
