Reduced gain spread spectrum communication system and method

An apparatus for wireless communication, the apparatus comprising:

• a spreader, having an input and an output, the spreader operable to receive a digitized voice signal at the input and to spread the digitized voice signal using a voice spreading sequence length less than an available spreading gain for a given transmission bandwidth to generate a voice spread signal;
• a conditioner coupled to the input of the spreader, the conditioner operable to specify a portion of a digital signal representative of digitized voice signals for spreading by the spreader;
• a buffer coupled between the conditioner and the input of the spreader, the buffer operable to receive the portion of the digital signal from the conditioner and to store the portion of the digital signal for use by the spreader;
• and
• a transmitter operable to transmit the voice spread signal generated by the spreader.
