Abstract :
The authors present a modem with in-band frequency agility that has been implemented with the TMS 32010 signal processor. A strategy based on embedded real-time channel estimation (RTCE) has been adopted to manage the frequency agility. This strategy has the advantage of being able to combat frequency-selective interferences, and it involves low handling complexity. The authors present measurements that are directed toward establishing the feasibility of this modem
