A Feed-forward Amplifier Using an Equal Group-delay Signal Cancellation Technique

In this article, new signal cancellers that can match the out-of-phase and group delay of two signal paths simultaneously are proposed. The simultaneous matching of the out-of-phase and group-delay time between two paths can permit broadband signal can...
Modern wireless communication systems utilize digital modulation techniques employing linear complex coding schemes to maximize the channel throughput available capability. Also, a broader channel bandwidth is used for more data transmission than before. In addition, as various communication services, such as cellular phone (IS-95), personal communication service (PCS), IMT-2000...
