Rayleigh channel.zip - Rayleigh fading is caused by multipath reception. The mobile antenna receives a large number, say N, reflected and scattered waves. Because of wave cancellation effects, the instantaneous received power seen by a moving antenna becomes a random variable, dependent on the location of the antenna.,2019-02-12 19:33:50,下载0次
Selection Diversity.zip - Selection diversity is a form of space diversity, where there are multiple antennas at the receiver. The presence of receiver diversity poses an interesting problem,2019-02-12 19:17:45,下载0次
Maximal Ratio Combining (MRC).zip - Maximum-ratio combining (MRC) is a simple and effective
combining scheme for adaptive antenna arrays to combat
noise, fading, and to a certain degree, cochannel interference. However,
it requires estimation of the spatial signature (i.e., the channel
gain and phase at each antenna element) of the desired signal across
the array,2019-02-12 19:03:54,下载4次
Alamouti STBC.zip - Space-time block codes are used for MIMO systems to enable the transmission of multiple copies of a data stream across a number of antennas and to exploit the various received versions of the data to improve the reliability of data-transfer. Space-time coding combines all the copies of the received signal in an optimal way to extract as much information from each of them as possible,2019-02-12 19:01:25,下载1次
2×2 MIMO channel.zip - Multiple-Input Multiple-Output (MIMO) wireless systems are one of the most promising technologies for providing large transmission capacity without expanding the frequency band in cellular mobile systems.,2019-02-12 18:58:10,下载0次
