Impulse radio ultra wide bandwidth data transmission encoding/decoding method and encoding/decoding module

Abstract

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.

Benefits of technology

[0026]As mentioned above, the high speed transmission encoding / decoding according to the present invention can achieve the improvement of the data rate without increasing circuit complexity, which is useful and attractive to the IR-UWB system.

Problems solved by technology

However, the improvement of the data rate not only challenges the performance of the whole receiver of the terminal such as sensitivity and noise, but also tests the power consumption of the analog baseband amplifiers and filters.

Furthermore, the high data rate also affects the spectrum planning of the system.

Therefore, only one binary data can be transmitted during a unit time period, which results in a low utilization of time.

It is noted that although researchers have taken a plurality of measurements including circuit and system design to improve the data rate by 20-30%, the complexity of the circuit greatly arises and the power consumption of the system sharply increases.
