Abstract:
1. A wireless transmitter, comprising: circuitry for providing a plurality of control bits; circuitry for providing a plurality of user bits; circuitry for modulating the plurality of control bits and the plurality of user bits into a stream of complex symbols; circuitry for converting the stream of complex symbols into a parallel plurality of complex symbol streams; circuitry for performing an inverse fast Fourier transform on the parallel plurality of complex symbol streams to form a parallel plurality of OFDM symbols; and circuitry for converting the parallel plurality of OFDM symbols into a serial stream of OFDM symbols, wherein the serial stream consists of an integer N+1 OFDM symbols; wherein each OFDM symbol in the serial stream of OFDM symbols comprises a plurality of data points; and wherein selected OFDM symbols in the serial stream of OFDM symbols each comprise control data points carrying a portion of a synchronization code wherein N+1 is a multiple of three; and wherein the selected OFDM symbols are each a second OFDM symbol in a sequence of three OFDM symbols in the serial stream.
