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.
