1. A spread spectrum channel apparatus, comprising:

  • (a) splitter means for accommodating a variable number of data channels by splitting each particular set of two received data symbols into a first and second array of data symbols in accordance with a particular algorithm selected from the group consisting essentially of a first algorithm and a second algorithm, the splitter means comprising means for implementing the first algorithm by providing both data symbols of the particular set to the first and second array of data symbols, the splitter means further comprising means for implementing the second algorithm by providing one of the data symbols of the particular set to the first array of data symbols and the other of the data symbols of the particular set to the second array of data symbols; and

    (b) code division channel coding means, operatively coupled to the splitter means, for determining particular channels to transmit the first and second array of data symbols by spreading the first and second array of data symbols with a predetermined length spreading code, the predetermined length of the spreading code being set in response to the particular splitting algorithm selected.
