Title: **David L. Snell: Innovator in Spread Spectrum Communications**
Introduction
David L. Snell, an accomplished inventor based in Calgary, Canada, has made significant contributions to the field of communications through his innovative patents. With a total of two patents to his name, Snell is recognized for pushing the boundaries of technology in ways that enhance communication efficiency and quality.
Latest Patents
One of Snell's latest inventions is the Multicode Spread Spectrum Communications System (MCSS). This modulation scheme assigns a number N of Spread Spectrum (SS) codes to individual users, utilizing M chips per SS code. In traditional Direct Sequence Spread Spectrum systems, the MCSS relies on up to N correlators at the receiver, leading to a complexity of NM operations. To address challenges such as InterCode Interference (ICI), Snell introduced three novel types of MCSS.
1. **MCSS Type I** enables detection through a series of partial correlations with a complexity order of M operations.
2. **MCSS Type II** simplifies the detection process through low-complexity parallel operations, which effectively reduce ICI.
3. **MCSS Type III** proposes a detection method utilizing a filter suitable for ASIC implementation or Digital Signal Processors, subsequently minimizing the multipath effects.
These enhancements not only lead to lower complexity detection but also ensure the system remains spectrally efficient.
