Abstract:
1. An apparatus comprising: a selector configured to select metric calculator values for respective ones of a plurality of channels in a Multiple-Input, Multiple-Output communication system in which transmit data is communicated to a receiving station upon the plurality of channels and received as receive data thereat, the metric calculator values selected for at least two of the channels differing from one another; and a decoder configured to separately decode values of the receive data received upon separate ones of the channels, wherein, for the values of the receive data received upon each of the channels, the decoder being configured to decode the values of the receive data includes being configured to perform a path length estimation for the respective channel, including being configured to calculate a path length for each of a number of possible paths upon which to estimate a minimum path length, the number of possible paths being selected based on the metric calculator value selected for the respective channel.
