Claim:
1. An electronic device comprising: a receiver that communicates with an external device, wherein the receiver receives a data stream from the external device, wherein the data stream includes a plurality of data packets including a data packet sequentially repeated a plurality of times, and wherein each data packet has a predetermined packet length and a header portion at a predetermined position within each data packet; a transmitter that communicates with the external device; a control unit that controls the receiver to detect a beacon transmitted from the external device, the beacon signaling that the external device is ready to transmit, wherein in response to detecting the beacon, the control unit controls the transmitter to transmit a beacon acknowledgement to the external device to signal that the electronic device is ready to receive the data packet in the data stream, wherein the control unit further controls the receiver to capture a block of data from the data stream, and wherein the captured block of data has the predetermined packet length and the header portion; and a decoder that restores the data packet from the captured block of data by locating the header portion of the data packet within the captured block of data and rotating the captured block of data to place the header portion at the predetermined position within the data packet.
