<p>This invention related to a method for achieving a large capacity CDMA spread communication system, for increasing the capacity of S-CDMA spread communication system, improving use ratio of frequency spectrum. A transmitting antenna or a receiving antenna of a transmitting side or a receiving side is configured into a smart antenna, or the transmitting and receiving antenna of the transmitting and receiving side are configured into the smart antenna simultaneously. A spread section in the transmitting side spread user data with the large spread code set which its number is larger than code size of normal spread code. A de-spread processing section in the receiving side de-spread user data with the large spread code set which its number is larger than code size of normal spread code. The de-spread processing section in the receiving side uses union detection and interference suppress technique.</p> |
