1. A base subunit for use in a wireless spread spectrum communication system comprising:
- an antenna for receiving a signal over a first frequency;
a plurality of mixers for mixing the received signal with a plurality of chipping sequences to produce a plurality of despread voice signals;
a combiner combining the despread signals and a voice signal generated at the base subunit;
a product device for mixing the combined signal with a chipping sequence; and
an antenna for transmitting the mixed combined signal at a second frequency.

Abstract
A base subunit receives a signal over a first frequency. A plurality of despread voice signals are produced using the received signal. The despread signals and a voice signal generated at the base subunit are combined. The combined signal is mixed with a chipping sequence. The mixed combined signal is transmitted at a second frequency.
