Method and apparatus implementing an overlay adaptive frequency hopping kernel in a wireless communication system

摘要

A novel method and apparatus for implementing an overlay adaptive frequency-hopping kernel in a wireless communication system is described. The present inventive method and apparatus selects hopping frequencies based on channel conditions. Hopping frequencies are selected using an inventive overlay adaptive frequency-hopping (OAFH) kernel that maps bad channels to good channels while retaining the pseudo-random properties of the original frequency-hopping sequence. The OAFH kernel uses existing FH kernels to initially select hopping frequencies. If the initially selected hopping frequency has bad channel condition characteristics, the OAFH kernel maps the initially selected hopping frequency to a substitute hopping frequency having good channel condition characteristics.
