Abstract :
This paper evaluates the frequency conversion efficiency without using both local oscillator and phase-locking in Software Definable Radio Network. Proposed method simultaneously enables us to perform not only frequency conversion, but also routing for different kind of wireless service. The conversion efficiency is important issues in Fiber-radio link toward low-cost implementation. This paper proposes the delayed-sequence decoding method at the routing node which enables to improve the conversion efficiency of 3.5 dB compared to the conventional decoding method
