Efficient pseudonoise code design for spread spectrum wireless communication systems

Power and bandwidth efficient communication schemes are of major concerns in wireless communication systems. One type of efficient pseudonoise code is proposed in this paper that provides combined power-bandwidth efficiency. A novel algorithm for verifying the power and bandwidth efficient properties of a pseudonoise code is proposed with systematic analysis of code parameters. Applications of the derived codes have been implemented on an 802.11 DS-SS system, which performs 36% bandwidth reduction and 14% power consumption reduction. Several new pseudonoise codes with different code lengths are also proposed.
