Abstract

A method includes receiving a first wireless signal and demodulating data in the first wireless signal using a first demodulation technique. The method also includes receiving multiple second wireless signals simultaneously (where the second wireless signals interfere to produce an interfered signal) and demodulating data in the interfered signal using a second demodulation technique. The method could also include (i) determining that a single transmitter transmitted the first wireless signal and selecting the first demodulation technique in response and (ii) determining that multiple transmitters transmitted the second wireless signals and selecting the second demodulation technique in response. Determining that the single transmitter transmitted the first wireless signal could include determining that a fundamental frequency of the first wireless signal is below a threshold. Determining that the multiple transmitters transmitted the second wireless signals could include determining that a fundamental frequency of the interfered signal is above the threshold.
