La code construction and performance analysis for LAS-2000
China Wireless Telecommunications Standards Organization presented LAS-CDMA to the international standards organization 3GPP2 as a proposal from China in March of 2000. In March of.2003 Li provided views on the potential of the LAS-CDMA technology applied to a high spectral efficiency system for a 4G system. .LAS-CDMA is characterized by a multiple access scheme, based on two families of CDMA codes, LA codes and LS codes. (17, 136, 2559) LA code group is used in LAS-2000, which is physical layer modes compatible with cdma2000 for the same chip rate, carrier spacing, frame length, core network architecture and protocols. In this paper, having investigated (17, 136, 2559) LA code construction, a method of triangular array formations of correlation value distribution positions for this code group is proposed in an effort to have a further theory analysis of LA codes.
