Polarization pre-coding for a single carrier communication system

A single-carrier communication transmitter comprising:

• a transmission circuit for transmitting a polarized single-carrier transmission signal to a receiver;
• a circuit for receiving feedback from the receiver, the feedback describing a figure of merit of a received polarized single-carrier transmission;
• and
• a circuit for causing the transmission circuit to change polarization of the transmitting the polarized single-carrier transmission signal, based on the feedback, thereby optimizing reception, by the receiver, of the polarized single-carrier transmission.

A single-carrier communication system comprising:

• a receiver for receiving a polarized single-carrier transmission signal, comprising:
• a circuit for determining a figure of merit of the received polarized single-carrier transmission signal;
• and
• a circuit in the receiver for transmitting feedback comprising data describing the figure of merit,
• and
• a transmitter comprising:
• a circuit for receiving the feedback from the receiver;
• a source for a polarized single-carrier transmission signal for sending the polarized single-carrier transmission signal to the receiver;
• a circuit for changing polarization of the polarized single-carrier transmission signal, based on the feedback, producing a changed polarization single-carrier transmission signal;
• and
• a circuit for transmitting the changed polarization single-carrier transmission signal to the receiver, thereby optimizing reception of the polarized single-carrier transmission signal.
