Abstract
An apparatus for generating at least one signal based on at least one aspect of at least two received signals is provided. The apparatus comprises: a diverse antennae array of M antennae, where M is greater than or equal to two; at least one multiple-input and multiple-output capable transceiver in communication with each antenna in the diverse antennae array of M antennae; encoding circuitry capable of causing first data to be encoded; decoding circuitry capable of causing second data to be decoded; and processing capable of causing diversity combining, where the processing circuitry is in communication with the multiple-input and multiple-output capable transceiver, the encoding circuitry, and the decoding circuitry. In operation, the processing circuitry is capable of causing the apparatus to: receive at least two first signals, combine at least two of the at least first two signals, generate at least two second signals based on at least one aspect of the at least two first signals, and simultaneously transmit the at least two second signals. Additionally, the apparatus is configured such that at least one of the at least two second signals is capable of being received by a multiple-input capable node.
