PURPOSE: As digital communication progresses, an increase of data form requires data of plurality forms simultaneously. An CDMA(Cord Division Multiple Access) having a higher data speed, a bandwidth efficiency is provided to perform communication of plurality forms. CONSTITUTION: 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 (W1) having a small number of PN spreading chips per orthogonal wave form 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.
