Design of a low complex impulse radio receiver for high data rate

The purpose of this paper is to provide an operative way of achieving high data rate for impulse radio (IR) transmission based systems in short distance. Since applications targeted for ultra-wide band (UWB) are liable to be low-cost, we especially focus on simple transceiver design. To that effect, we present a threshold detection scheme adapted to an on-off keying modulation. Receiver adopts detection reception with parallel multilevel threshold decision. It can realize noncoherent communication of which the pulse repetition frequency can reach to 200MHz within extreme-short distance of 1/spl sim/2m, and lower the difficulty of transceiver design effectively.
