Research on a high noise immunity transmission system and its performance in short-range wireless communication based on the MIMO-UWB technology

摘要

In this paper, a new type of high noise immunity short-range wireless communication system model is established. By analyzing and being compared with several kinds of commonly used Short-range wireless communication, we establish a UWB (Ultra Wide Band) communication system model and the transmission error rate expression by using STBC (Space-Time Block Coding) scheme. Also a solution to decrease BER (Bit Error Rate) effectively by using MIMO (Multiple Input Multiple Output) technology is put forward. The simulation results show that: MIMO-UWB short-range wireless communication system can reduce the transmission error rate and enhance the data transmission performance of communication system even in very low SNR(signal to noise ratio) condition. Compared with other means of communication, multiple antenna can not only maintain a high rate of high quality wireless communication function in high electromagnetic interference environment, but also work normally with very low power. So MIMO-UWB short-range wireless system can better adapt to the requirement of future Internet of Things and short-range large amount of information wireless communication. It has very important value of research and application.
