Abstract
A radio transceiver apparatus configured to transmit and receive radio frequency signals, the apparatus comprising, a sample clock configured to generate samples at a clock frequency fs, a processor configured to generate a transmission data stream signal, wherein the transmission data stream signal comprises frames separated by frame boundaries between the frames, and wherein the frames are comprised of at least one sample, and a sample clock correction unit, wherein in a first transmission configuration when the clock frequency fs is greater than a desired clock frequency fr, the sample clock correction unit is configured to insert at least one sample into at least one frame boundary between frames, or in a second transmission configuration when the clock frequency fs is less than a desired clock frequency fr, the sample clock correction unit is configured to remove at least one sample from at least one frame boundary between the frames.
