Method and apparatus for providing high data rate traffic channels in a spread spectrum communication system

A spread spectrum channel apparatus which accommodates variable received data bit rates, comprising:

• (a) despreading means for sampling a signal received from over the communication channel into data samples by despreading the received signal with a spreading code, the received signal comprising spread orthogonal codes wherein the spread orthogonal codes were formed from data bits received at a particular bit rate and encoded at a predetermined encoding rate into data symbols, predetermined length orthogonal codes were derived from the data symbols, and subsequently the derived orthogonal codes were prepared for subsequent transmission by being spread with a spreading code, the predetermined encoding rate and the predetermined length of the orthogonal codes having been set in response to the received data bit rate:
• and
• (b) decoding means, operatively coupled to the despreading means, for generating an estimated data bit by deriving the estimated data bit from the data samples.
