A Column Orthogonality Space-Time-Frequency Coding Schemes
Advanced Materials Research, 2013A column orthogonal space-time-frequency coding scheme is presented, its induced cost207 transmit environment channel matrix has greater determinant value, which will lead result in amplifying the signal-to noise ratio of system, and improving the performance of the system. Computer simulations confirm the theory of the article.

A space-time block code using orthogonal frequency-shift-keying
IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005We investigate in this paper an Alamouti-type space-time block code (STBC) using orthogonal M-ary frequency-shift-keying (MFSK). The signal is coherently detected using the channel estimates derived from the unmodulated (or implicit pilot) component of the orthogonal signal.
