Abstract:
1. A method of transmitting data comprising: providing a datastream comprised of bits; interleaving the bits of the datastream across a plurality of orthogonal frequency division multiplexed radio frequency transmitters, wherein each of the radio frequency transmitters transmits a plurality of radio frequency subcarriers, to provide interleaved bits wherein consecutive interleaved bits are grouped and mapped to symbols and the symbols assigned for transmission such that adjacent datastream bits are assigned to differing transmitters and differing subcarriers with low channel response correlation to thereby exploit an increased amount of spatial and frequency diversity; transmitting the symbols using the plurality of radio frequency subcarriers of the plurality of orthogonal frequency division multiplexed radio frequency transmitters wherein assigning symbols such that adjacent datastream bits are assigned to differing transmitters and differing subcarriers with low channel response correlation further comprises assigning symbols such that adjacent datastream bits out of each encoder when multiple encoders are used are assigned to differing transmitters and different subcarriers with low channel response correlation to thereby exploit an increased amount of spatial and frequency diversity for each encoded datastream.
