Abstract
The present invention provides methods and apparatus for transmitting and receiving over a MIMO radio link. In particular, a precoding matrix is applied to transmitted signals and constrained in such a way so as to limit the additional peak to average power ratio (PAPR) caused by applying the precoding matrix. For example, each row of the precoding matrix may have a single non-zero element, and/or each column may have the same number of non-zero elements.
