Abstract :
We investigate a construction of a multi-mode receiver for various spread spectrum communication and broadcasting systems. We propose a way to reduce the hardware scale by sharing the same IF-unit. Therefore, it is possible to minimize the increase of the total bandwidth of the IF signal. We assume a receiver tuned to IMT-2000, 2.6 GHz satellite broadcast system and IEEE 802.11 wireless LAN for the proposed method, and consider IF carrier positioning and the system power ratio. Through computer simulation we show that the IF-unit is shared without increasing the bandwidth as much as it is done in conventional systems.
