Abstract
A method employed by a base station wherein a plurality of channels are received as a received signal. Each channel is associated with a code. For each of the plurality of channels, others of the plurality of channels are subtracted from the received signal and a result of that subtracting is despread as data for that channel.
Claims9
A method employed by a base station for recovering data transmitted over a plurality of channels employing wireless code division multiple access communication, comprising:
- a) receiving the plurality of channels as a received signal, each channel associated with a code;
- b) subtracting for each of the plurality of channels others of the plurality of channels from the received signal and despreading a result of that subtracting as data for that channel.
A method employed by a base station for recovering data transmitted over a plurality of channels employing wireless code division multiple access communication, comprising:
- a) despreading a spread spectrum signal employing a detector for generating despread, spread spectrum outputs for each channel;
- b) receiving the plurality of channels as a received signal, each channel associated with a code;
- and
- c) subtracting for each of the plurality of channels others of the plurality of channels from the received signal and despreading a result of that subtracting as data for that channel.
