Apparatus for performing frequency conversion in a communication system

An apparatus for despreading a spread spectrum signal, the apparatus comprising:

• signal receiving means, for receiving the spread spectrum signal;
• a digitizer coupled to the signal receiving means;
• a Hilbert filter configuration, coupled to the digitizer;
• a counter having a clock signal as input and a plurality of signals as output;
• plurality of pseudo-random noise generators;
• a decoder coupled to the pseudorandom noise generators and outputting control information;
• a multiplexer having input from the Hilbert filter configuration and outputting a signal sample arguments;
• and
• first and second accumulators, having as input the signal sample arguments, for accumulating the signal sample arguments based on the control information.

An apparatus for spreading a signal to generate a spread spectrum signal, the apparatus comprising;

• a counter having a clock signal as input and a plurality of signals as output;
• a plurality of pseudo-random sequence generators;
• a decoder for generating multi-phase spread transmit signals based on input from the plurality of pseudo-random sequences generators and a combination of the plurality of signals from the counter;
• and
• a converter for converting the generated multi-phase spread transmit signals into a form for transmission.
