Abstract
A method and apparatus for high rate CDMA wireless communication is described. Variable data rates are generated using a set of different encoder, interleaver, and symbol repetition configurations. An encoder associated with each rate generates a variable number of symbols during each frame period. This variable number of symbols is repeated as necessary to form a constant number of symbols equal to a fixed number of symbols that can be then repeated a fixed number of repetitions before transmission. Where the constant number of symbols is not an integer multiple of the variable number of symbols for a particular rate, a subset of the variable number of symbols is repeated to fill in the remaining symbols necessary to equal the constant number of symbols.
