METHOD AND APPARATUS FOR SIGNAL DETECTION IN ULTRA WIDE-BAND COMMUNICATIONS

摘要

Methods and apparatus for detecting ultra wide-band signals using circuitry having nonlinear dynamics characteristics are disclosed. The receiver circuit can be implemented using a simple tunnel diode or using an op-amp to provide dynamic characteristics. The detector can be used in a variety of modulation schemes, including but not limited to an ON-OFF keying scheme, an M-ary pulse positionm odulation scheme, and a pulse width modulation scheme. The approach requires only a single frame to detect the signal.
