(Code Division Multiple Access) - A Second generation PCS network standard promoted by Qualcomm, now blessed by
Ericsson because it acquired intellectual property rights to Qualcomm's research.
In the recent past, when first
generation AMPS cellular networks were being replaced by the second
generation, there were two basic PCS technologies vying for leadership
- TDMA (Time Division Multiple Access) and CDMA. However, for all
intents and purposes, CDMA has won the battle - primarily because of
superior performance and more channel capacity out of the same bandwidth.
For a high-level understanding
of the coding scheme and differences between TDMA and CDMA, please read
chapter 8 of "Mobile Computing- A
Systems Integrator's Handbook". For even a deeper
understanding (for RF and electrical engineers), go to "Wireless PCS
Book by Rajan Kurupillai and others" - both books published by
McGraw-Hill. Go to "More
Books" page for further details on books.
