receiver

UWB signal detection technologies are an important focus of the present study. In order to confront the spread of multi-path and fading, we can use the channel estimation, RAKE receiver, Multi-user detection, and other signal processing technologies. We can get the different path delay through channel estimation, fading amplitude, phase and other information. Rationally design the RAKE receiver and merger the multipath signals. However, in these technologies, the cheap shoes blog 2010 Multi-user detection has the optimal performance, but the complexity is too high, it is necessary to be further practical.In UWB communication systems, the multiple access interference is an important reason for limiting the system performance. In order to effectively suppress multiple access interference, we will use the multi-user detection technology into the ultra-wideband multi-user communication systems. At present, the majority of researches on ultra-wideband multiple access systems are based on the blog wedding dresses 2010 traditional single-user detector. So with the increase in the number of women's nike shoes users, multiple access interference (MAI) becomes the essential factor which impacts the chi hair straighteners capacity and performance of the UWB system. Therefore, this paper discusses the multi-user detection technology in UWB system, in order to overcome the shortcomings of the traditional receiver, to effective suppress the multiple access interference, and to improve the capacity and discount wedding dresses performance of cheap wedding gown dresses system.Nevertheless, there are some defects in traditional multi-user detector: it assumes that the receiver lace wedding dresses can acquire the signature waveform and timing of desired user and the interfering users.
