Spread Spectrum Systems for GNSS and Wireless Communications, Volume 45
Look to this cutting-edge resource for a modern treatment of spread spectrum (SS) communications, including direct sequence and frequency hopping. The book helps you understand the performance of SS systems under the influence of jamming and with and without coding. You find details on the synchronization of SS systems, including initial acquisition and tracking. The book discusses correlation loss to help you determine the impact of filters on the correlation process. Moreover, for the first time in any book, you find details on code acquisition and code tracking with channel filtering.
