摘要
The present invention provides a spread spectrum transmitter comprising a spread spectrum encoder for encoding digital data to produce a spread spectrum signal and means for transmitting said signal, characterized in that the spread spectrum encoder includes a code generator incorporating an apparatus for generating complex four-phase code division multiple access (CDMA) codes, the apparatus comprising:a plurality of flip flops,an accumulator having a first input for receiving an output from said plurality of flip flops and a second input for receiving a quotient of a parameter M divided by a parameter N, wherein M and N are integers and wherein M is relatively prime to N; said accumulator combines data received via said first and second inputs and outputs the combined data to said flip flops; an extractor extracting a first bit and a second bit from the flip flops;and means for converting the extracted first bit and second bit to I and Q values.
