—We consider channel/subspace tracking systems for temporally correlated millimeter wave (e.g., E-band) multiple-input multiple-output (MIMO) channels. Our focus is given to the tracking algorithm in the non-line-of-sight (NLoS) environment, where the transmitter and the receiver are equipped with hybrid analog/digital precoder and combiner, respectively.(More)
This paper proposes a novel STBC-based transmit diversity scheme for physical-layer network coding (PNC) aided two-way relay networks, where two end nodes are equipped with two transmit-antenna. To directly decode network-coded signals from the received superimposed signals at the relay, the two end nodes in this proposed system use reciprocal channel state(More)
As the demand for e-Health care increases quickly, the transmission of medical images has been a crucial problem which needs to be solved as soon as possible. In the last decade, joint source-channel coding (JSCC), which combines the source coding with the channel coding reasonably to build an integral system so as to obtain significant improvement of(More)
A scheme of joint source and channel coding (JSCC) with double Low Density Parity Check (LDPC) structure has been proposed recently, which results in a popular and promising research topic for further improving JSCC design at physical layer. However, it becomes an important problem how to enhance the error performance and reduce the complexity of the whole(More)
We analyze the performance of a multi-source multi-helper transmission with lossy forward (LF) relaying. In LF, estimates at the relay are encoded and forwarded to the destination for improving the reliability of the received sequence transmitted from the multiple source nodes. Unlike the conventional decode-and-forward (DF) relaying, LF sends the data even(More)
