IMPULSE RADIO ULTRA WIDE BANDWIDTH DATA TRANSMISSION ENCODING/DECODING METHOD AND ENCODING/DECODING MODULE

摘要

The present invention provides an IR-UWB data transmission encoding/decoding method and module. The encoding method comprises: in each unit time period lasting T seconds, receiving an N-bit of binary data of an M-bit binary data stream and generating UWB impulse radio signal having a specific frequency fi, determining and generating an amplitude value Ax of the UWB impulse radio signal having the specific frequency fi according to the remaining M-N bits binary data, and finally transmitting the UWB impulse radio signal having the specific frequency fi and the amplitude value. The decoding method corresponds to the encoding method. According to the present invention, the data transmission rate can be increased by four times compared with the conventional data transmission rate without increasing the circuit complexity, which is useful and attractive to the IR-UWB system.
