A method and apparatus is provided for efficient processing of signal in a communication system. The processing of the signal for transmission may include encoding a block of data at an encoding rate 1/R. The encoding produces R number of data symbols for every data bit in the block of data. A block of RAM ( 299, 600 ) is partitioned into a plurality of blocks of RAM to allow reading simultaneously data symbols from the plurality of blocks of RAM to produce an in-phase and a quad-phase data symbols simultaneously. At least two scramblers ( 306 and 307 ) are used for simultaneously scrambling the in-phase and quad-phase data symbols. A Walsh covering/summing block ( 700 ) followed by the scramblers provides efficient Walsh covering and summing of signals for a combined transmission from the communication system. |
