书籍 Scrambling Techniques for CDMA Communications
With the advent of IMT-2000, CDMA has emerged at the focal point of
interest in wireless communications. Now it has become impossible to discuss
wireless communications without knowing the CDMA technologies. There are
a number of books readily published on the CDMA technologies, but they are
mostly ...

digital signals, and spread spectrum system design and analysis. This book
was written for those ...
书籍 ESD+and+Electronic+Equipment
Since electronic equipment was first developed, static electricity has been a
source of problems for users and designers. In the last few years, however,
electrostatic discharge (ESD) has become a source of major problems. This
has occurred because newer electronic devices, such as integrated circui ...
