The present invention facilitates efficient and effective combination of multiple spread spectrum signals into a single stream. A spread spectrum signal combination system and method of the present invention facilitates fast communication of information and increases overall network communication performance by coordinating conversion from spread spectrum protocols to single stream communication protocols. A plurality of signals can be combined into a single stream of information by selecting among them on a chip time basis in a predetermined pattern (a pseudo-random pattern). The predetermined pattern can be balanced and have the same number of ones and zeroes (e.g., a balanced pattern stored in a precomputed table with randomly arranged rows). For example, the predetermined pattern can be implemented with a shuffled Hadamard function. Alternatively, the selection part of a Hadamard table can be replaced with a pseudo-random number generator such that the rest of the table remains as a shuffled Hadamard.
