Abstract
Official abstract text for this publication.
A receiver employs low-rate processing to synthesize the effect of high-rate interference in a received multi-rate signal. Each high-rate subchannel is analyzed on its low-rate descendents to produce symbol estimates for each low-rate symbol interval. The symbol estimates are applied to low-rate descendent subchannels, which are then combined to synthesize the effects of the high-rate interference. An interference canceller processes the synthesized interference with the received signal for producing an interference-cancelled signal. Alternatively, analogous steps may be applied at high-rate to analyze, synthesize, and cancel the effects of low-rate interference in a multi-rate signal.
First claim
Opening claim text (preview).
We claim: 1. A method for cancelling interference effects, the method comprising: receiving a signal including an interfering signal associated with a first code and a first rate; despreading the signal using a plurality of descendent codes of the first code to obtain, for the interfering signal, a plurality of subchannels associated with a second rate that is lower than the first rate; generating a plurality of symbol estimates for the plurality of subchannels; and reducing…
