METHOD FOR REINFORCING COMMUNICATION SIGNAL IN WIDEBAND CODE DIVISION MULTIPLE ACCESS MOBILE UNIT COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an improved CDMA communication system which uses spatial time transmission diversity. SOLUTION: A smart antenna is joined to a polarization interleave switch beam to reinforce down link wideband code division multiple access performance by applying the space time transmission diversity scheme to angle and time transmission diversity. Aperture gain is converted into diversity one by dividing a different departure angle by different space time diffusion.
