Abstract
The present invention relates to structures of the spread CDMA system of band diffusion with antenna array. The present invention, structures of 2-D demodulator are provided, for spread spectrum CDMA systems with antenna array which can increase coverage area of base station and system capacity, by extracting and combining all information needed in time and space domains, using only the information which shall be calculated in a CDMA system inherently.
