| titleOfInvention |
Wireless communications methods and systems for long-code and other spread spectrum waveform processing |
| abstract |
The invention provides improved CDMA, WCDMA or other spread-spectrum communication systems of the type (fig. 1) that processes one or more spread-spectrum waveforms, each representative of a waveform received from a respective user. The improvement is characterized by a first logic element (100) that generates a residual composite spread-spectrum waveform (112) as a function of an arithmetic difference between a composite spread-spectrum waveform for all users and an estimated spread-spectrum waveform for each user. It is further characterized by one or more second logic elements (118, 120) that generates for at least a selected user, a refined spread-spectrum waveform as a function of a sum of the residual composite spread-spectrum waveform and the estimated spread-spectrum waveform for that user. |
