This paper presents a new frequency domain algorithm for blind deconvolution. Our frequency domain algorithm can overcome the difficulty appearing at the frequency bin and avoids the ambiguity of frequency coupling. Like other frequency domain algorithms, our algorithm needs not the identically distributed (iid) assumption of source signals. Our result shows that as long as observed signals are more...
In MIMO (multiple input multiple output) system, a wireless channel can be divided into several individual subchannels in order to expand the processing capacity comparing to SISO (single input single output) system. The correlation between these subchannels is critical to the system performance, and can be reduced by various diversity schemes. The space diversity has better performance for NLOS(non-line-of-sight)...
This paper studies the blind identification problem for multiple-input multiple-output (MIMO) FIR channels, in which the source signals are modulated by high order periodic precoders. A set of new design criteria of the periodic precoders is proposed from the channel blind identification viewpoint for multiuser channels. It is shown that, due to the fact that high order periodic precoders are used...
