Abstract  Abstract

A communication system adapted to limit an increase in the ratio of peak power to average power, PAPR, caused by the application of a precoding matrix for a single carrier transmission over a MIMO radio link, in which the system comprises : a user equipment comprising a transmitter comprising a plurality of antennas (12) and a processing circuit (16), wherein said processing circuit comprised in the user equipment is adapted for a transmission of a single carrier and to apply a precoding matrix to a symbol vector, to generate a precoded vector, wherein said precoding matrix has four rows and two or three columns, wherein said transmitter is adapted to transmit said precoded vector over a link of MIMO radio; and a radio base station comprising a transceiver comprising a plurality of antennas, in which the radio base station comprises a processing circuit, said processing circuit comprised in the radio base station is adapted to determine a precoding matrix used by the radio base station of the user equipment, to generate a precoded vector from a symbol vector for transmission of a single carrier over a MIMO radio link, in which said transceiver is adapted to receive over the link of MIMO radio said precoded vector that has been precoded with said determined precoding matrix, wherein said processing circuit comprised in the radio base station is further adapted to decode said received precoded vector, characterized in that said precoding matrix is restricted so that each row comprises at least one element i equal to zero, so that the number of nonzero elements in each row is less than the number of columns in said precoding matrix, and in which the precoding matrix is further restricted in that each of said columns It has at least one nonzero element and each of these rows has at least one nonzero element.
