    Abstract: A receiver receives a desired radio sub-channel transmitted with an unwanted radio sub-channel by producing signal branches from a received radio signal by treating orthogonal components of the received signal separately and also by using one or both of oversampling and multiple receive antennas. Channel estimates for both the desired and unwanted radio sub-channels are produced for signal branches. The unwanted radio sub-channel bits are estimated from a non-stacked form of the received radio signal. The channel estimates and the estimate of the unwanted radio sub-channel bits are used to reconstruct unwanted radio sub-channel components separately for signal branches. Desired radio sub-channel signal branches are produced by subtracting a corresponding one of the reconstructed unwanted radio sub-channel components from signal branches. A non-stacked desired signal is produced by combining the desired radio sub-channel signal branches. The non-stacked desired signal is processed to receive the desired radio sub-channel.

    Abstract: A wireless communication apparatus is arranged to detect, among a plurality of modulated carrier signals of different frequencies, at least one of the modulated carrier signals modulated with a tone burst. A receiver provides a composite signal comprising the plurality of modulated carrier signals received simultaneously. An ADC generates samples of the composite signal, and the samples of the composite signal are divided into a plurality of blocks. The samples of each block are transformed into frequency domain components, and the frequency domain components of each block are divided into a plurality of groups, each group corresponding to a range of frequencies occupied by a different one of the modulated carrier signals. Tone burst detection is performed on each group, and it is determined which of the modulated carrier signals is modulated with the tone burst, according to which of the groups the tone burst is detected in.
