Mobile Wireless Communication Teminal And Method For Analyzing Abnormal Body Based On UWB Using It}

The present invention relates to a method for performing bio-abnormal analysis using a portable wireless communication terminal and its UWB impulse radio. Specifically, the UWB impulse radio can be irradiated to a specific part of the living body to receive the reflected radio signal and compare with the body information obtained from normal body information to enable remote medical care or first aid or to receive health and medical information. The present invention relates to a portable wireless communication terminal for performing an abnormal biometric analysis using a UWB impulse radio and a method for performing biometric abnormality analysis using a UWB impulse radio thereof.

UWB stands for Ultra Wideband and stands for Ultra Wideband. UWB (Ultra WideBand) refers to a technology that transmits and receives data using a wide frequency band of several GHz, and uses a short time pulse of several ns or 1ns or less, and a cosine that modulates a carrier wave, that is, information. The condition of not using a cosine wave is added, and UWB is also called an impulse radio. The characteristic of impulse radio, that is, UWB, can check the information change of an object with an impulse.

Due to the fact that information is sent using short pulses of several ns or less than 1 ns, UWB has a low power spectral density at the transmit power, immunity to multipath interference, simplification of transmission and reception circuits, and distance. It is characterized by the fact that it can be measured. The pulse's very narrow time width makes it easy to isolate pulses reflected by the structure, avoiding the effects of multipath interference. In addition, the UWB has a characteristic of pulse transmission, which simplifies the transmission and reception circuit. For this reason, the circuit (frame clock) that generates pulses regularly is the most important element in the UWB transceiver circuit.
