摘要:
Embodiments may comprise an orthogonal frequency division multiplexing (OFDM) system operating in the 1 GHz and lower frequency bands. In many embodiments, the physical layer logic may implement repetition logic to repeat portions of the data streams to increase the ability of a receiving device to detect and decode the data streams. In some embodiments, the repetition logic may comprise a preamble repeater to repeat the training and/or signal fields. In further embodiments, the repetition logic may comprise a payload repeater to repeat the payload one or more times. Other embodiments comprise a receiving device comprising a correlator to correlate the repeated preamble symbols to detect a communication from a transmitting device. The receiving device may also comprise correction logic to correct data streams from the communications signal based upon repetitions of the payload in the data streams.
