摘要： A system including a direct current tone, guard tone, data tone allocation, mapping, and inverse Fourier transform (IFT) modules. The direct current tone module determines a number of direct current tones based on whether a network device is operating in a single user or multi-user mode. The guard tone module determines a number of guard tones based on whether the network device is operating in the single user or multi-user mode. The data tone allocation module determines a number of data tones based on the number of direct current and guard tones. The mapping module receives data and based on the number of data tones, maps the data to the data tones. The IFT module performs a frequency to time domain conversion of an output of the mapping module to generate orthogonal frequency division multiplexing (OFDM) symbols during the single user mode and OFDM access symbols during the multi-user mode.

摘要： Certain embodiments of the present disclosure allow for detection of a transmitted preamble sequence by processing a correlation of a received signal and a preamble hypothesis in a way that exploits the good correlation properties of the known set of preamble sequences. For certain embodiments, the highest peaks of the correlation output may be compared across all preamble hypotheses to decide which preamble sequence is transmitted. Embodiments deal with MIMO OFDM where a sum of the N t maximum correlation peaks is composed, where N t is the number of transmit antennas.
