Patent ID: 6980582

Claim:
An achieving method for a large capacity Synchronous Code Division Multiple Access (SCDMA) spread-spectrum communication system, comprising: configuring a source unit, a channel coding unit, a spreading unit, a radio frequency transmitting unit and a transmitting antenna in transmitting end; configuring a receiving antenna, a radio frequency processing unit, a demodulation processing unit and a channel decoding unit in receiving end; at least setting the transmitting antenna in the transmitting end or receiving antenna in the receiving end being a smart antenna; setting a large spreading codes set, with the number of codes greater than length of a code in the set, being used for spread-spectrum processing in the spreading unit of transmitting end; setting a large spread codes set, with the number of codes greater than length of the code in the set, being used for demodulation processing for baseband signal in the demodulation processing unit of receiving end.
