Abstract
According to the present invention a transmitter and a transmitting method for communicating data symbols over a communication channel, for example, according to the CDMA system is presented. The transmitter (24, 25) comprises means (9) for spreading each data symbol with a respective spreading code, wherein the spreading codes are mutually orthogonal. Means (10) for scrambling are provided to scramble each spread symbol with a respective scrambling code, the scrambling codes respectively having the same length as the spreading codes. Furthermore, means (11) for the transmission of the spread and scrambled symbols are provided. According to the present invention the means (10) for scrambling are provided with a plurality of different scrambling codes, which can be used simultaneously within the same link. The main advantages of the present invention are the greater flexibility in the assignment of spreading sequences within a CDMA system, the increased maximum data rate for downlink or uplink. <IMAGE>
