Abstract
A method and apparatus for high rate CDMA wireless communication in which a set of individually gain adjusted subscriber channels are formed via the use of a set of orthogonal subchannel codes (Wi) having a small number of PN spreading chips per orthogonal waveform period. Data to be transmitted via one of the transmit channels is low code rate error correction encoded (134) and sequence repeated before being modulated with one of the subchannel codes, gain adjusted (152, 154, 156, 158), and summed (160) with data modulated using the other subchannel codes. The resulting summed data is modulated using a user long code and a pseudorandom spreading code (PN code) and upconverted for transmission.
