Analog front end modules design in non-coherent UWB receivers for sensor networks

An Energy detection non-coherent UWB receiver modeled in IEE802.15.3.a with BPPM modulation. Because of multipath model of channel, coherent receivers need a Rake receiver with high number of fingers that make high complexity systems. Non-coherent receivers are compatible with low complexity and low power dissipation design. We develop a new system level simulation technique for energy detection non-coherent receiver; taking into account the effect of non-ideality parameters of receiver such as nonlinear 3^rd order coefficients, slew rate, integrator noise and saturation. Simulations are performed to analyze the receiver performance versus non-ideal parameters, SN Launch Internet Explorer Browers.Ink R of channel and data rate. Low power dissipation required for high battery life time in sensor networks; So Low power dissipation, low computation and hardware complexity are required for location and Ranging systems.
