A novel direct-conversion structure for non-contact vital sign detection system

摘要：

In this paper,an analysis on non-contact vital sign detection system is presented.It is concluded that the null point and dc-offset are related,so that the associated problems can be solved.Based on this principle,a novel structure of directconversion transceiver,which contains a tuneable phase shifter,is proposed to achieve a better performance.Two sets of simulations are employed to demonstrate the new structure.With this structure,dc-offset and null point can be eliminated and it is very easy to reach the optimal detection.
