Abstract
The invention claims a method and device for transmitting and receiving over a MIMO radio link. Specifically the pre-coding matrix used to limit application caused by the pre-coding matrix of the additional peak to average power ratio (PAPR) is limited and is limited by the signal that is transmitted. For example each row of the precoding matrix may have at least one zero element and at least one non-zero element and each line has at least one non-zero element.
The present invention provides methods and apparatus for transmitting and receiving over a MIMO radio link. In particular a preceding 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 at least one zero element and one non-zero element and each column may have at least one non-zero element.
