  • Efficient spreader for spread spectrum communication systems
    Patent number: 7103088
    Abstract: A spreading system and method for CDMA applications that requires fewer integer multiplications. User data is spread using real or complex integer based spreading codes of length SF to SFmax chips. At least one of the codes is of the form jn·v[n] where v[n] is a spreading code. The invention provides increased user separation using a plurality of spreading codes.
    Type: Grant
