Low -cost two-stage receiver system for DS-CDMA |
摘要 |
A method and apparatus for receiving and processing a DS-CDMA signal in accordance with a two-stage process. The first stage comprises signal detection and employs a correlation between the sampled incoming waveform and a pseudo-noise code sequence. This stage is performed in real-time. Once a signal has been detected, a burst of the sampled incoming waveform is collected and then post-processed to recover the incoming information. The method may be implemented at low-cost on a general-purpose digital signal processor. The invention is especially suitable for DS CDMA location systems, where low-cost and low power consumption are desirable.
