Abstract:
A method for transmitting a signal from a plurality of antennas, the signal formed of symbols, sequenced together to form a first input symbol stream, said method comprising the steps of:receiving the first input symbol stream at a transmitter; offsetting said first input symbol stream to generate a second input symbol stream, wherein said second input symbol stream is identical to said first input symbol stream but offset from said first input symbol stream M symbol periods; performing a first transform on at least two symbols of said first input symbol stream over a time period to generate a first transform result; performing a second transform on at least two symbols of said second input symbol stream, substantially simultaneously over said time period, to generate a second transform result, the second transform identical to the first transform, and transmitting, substantially simultaneously, said first transform result on a first at least one antenna and said second transform result on a second at least one antenna.
