Abstract  Abstract

A wireless transmit receive unit (WTRU) comprising a data signal generator configured to produce a data signal; a plurality of mixers configured to produce a plurality of spread data signals wherein each mixer is configured to mix the data signal with a different pseudo random chip code sequence to produce a different spread data signal; a plurality of pilot signal generators configured to produce a plurality of spread pilot signals wherein each pilot signal is spread with a different pseudo random chip code sequence and each pilot signal generator is associated with a different spread data signal; a plurality of combiners configured to produce a plurality of combined signals wherein each combined signal is produced as a result of combining one of the pilot signals with one of the spread data signals;
a modulator configured to modulate the combined signals to a carrier frequency; and an array of antennas configured to radiate the plurality of combined signals over a shared spectrum at the carrier frequency wherein each antenna is associated with a different modulated combined signal.
