A MIMO transmitter and method for transmitting a group of sequential OFDM symbols on a downlink channel using a plurality of antennas is disclosed herein. Flexibly attached to the base is a joystick. In a second aspect input samples are taken and shifted to an orthogonal sampling grid according to a line phase measure. The method may also include determining whether a deceleration lock-up control condition is met, and performing deceleration lock-up control, including engaging a lock-up clutch, if the condition is met.
