I'm on thin ice, about to be corrected by the techies on this dangerously intelligent board. But the corrections would be welcome. Actually went to US Patent office website and looked at Q's patent 4,901,307 which appears to be the heart and soul of CDMA. I cut and pasted the following from the patent which apparently ( and I do mean apparently) refers to WCDMA. If I'm full of bologna, please let me know. The communication system 10 uses spread spectrum signal transmission techniques to increase user capacity by establishing coded digital communication signals that use quasi-orthogonal bit sequences to decrease mutual interference. At the same time, the communication channels are spread across or occupy the entire allocation bandwidth, which improves communication quality, allows for increased bandwidth signals and decreases the effects of frequency selective fading. Spread spectrum communication involves processing the outgoing information signal with a spreading function which changes or expands a narrow bandwidth signal into a broad bandwidth signal. The spreading function is a reproducible function which spreads the narrow bandwidth transmission signal over a broader bandwidth and reduces the peak spectral density of the signal. This is direct sequence spread spectrum coding. Alternatively, the carrier frequency can be pseudo-randomly hopped over the spread bandwidth. Direct sequence spread spectrum is preferred for applications addressing multipath impairments. Seems to be talking about WCDMA. Can a tech-blessed poster comment?
