Abstract
PROBLEM TO BE SOLVED: To provide methods and apparatus for transmission and reception over a MIMO radio link.
SOLUTION: A precoding matrix is applied to transmitted signals and constrained in such a way so as to limit additional increase in the peak to average power ratio (PAPR) caused by applying the precoding matrix. For example each row of the precoding matrix may have at least one zero element and one non-zero element and each column may have at least one non-zero element.
