Abstract
A circuit is designed with an encoder circuit ( ) coupled to receive a data sequence. The encoder circuit produces a first encoded data sequence and a second encoded data sequence from the data sequence. A first spreading circuit ( ) is coupled to receive the data sequence and the first encoded data sequence. The first spreading circuit produces a first modulated data sequence in response to a first code. A second spreading circuit ( ) is coupled to receive the data sequence and the second encoded data sequence. The second spreading circuit produces a second modulated data sequence in response to a second code.
