Abstract—A new 4 × 1 scheme of transmitting two real orthogonal space-time block codes (O-STBC) on the I- and Q-channels with pulse-shaped offset QAM is proposed. This scheme ac...

— Most of the existing works on space-time block codes (STBC) assume the channels are quasi-static, i.e., they remain invariant within one block. This assumption is not always tr...

In wireless channels, the path loss exponent (PLE) has a strong impact on the quality of the links, and hence, it needs to be accurately estimated for the efficient design and oper...

Distributed source coding is traditionally viewed in the block coding context -- all the source symbols are known in advance at the encoders. This paper instead considers a stream...
