摘要： A communications device includes a signal input that receives an orthogonal frequency division multiplexed (OFDM) communications signal. A demodulator is connected to the signal input for receiving the OFDM communications signal and demodulating the OFDM communication signal. It includes at least one memory element for storing the at least one sine/cosine basis waveform approximation as complex exponential functions. A logic circuit performs logical shifts in additions and multiples of ±2n and extracts amplitude and phase values from a plurality of N data subcarriers within the OFDN communications signal. The demodulator includes efficient implementation of the FFT for use as an OFDM demodulator where the complex exponentials are approximated by multi-level complex sinusoids and optionally oversampled to increase SNR of the FFT output.

摘要： A wireless communication network includes a plurality of mobile nodes each including a transceiver, a phased array antenna connected to the transceiver, and a controller connected to the transceiver. The controller schedules time slots for each time frame to establish a communication link with each neighboring mobile node. An initiating mobile node transmits a request for time slots to the receiving mobile node, which transmits a reply to the initiating mobile node. The initiating mobile node transmits a confirmation to the receiving mobile node, and the receiving mobile node transmits the reply again if the confirmation is not received. Alternatively, the receiving mobile node may transmit an acknowledgment to the initiating mobile node, and the initiating mobile node transmits the confirmation again if the acknowledgment is not received.
