Balanced codes for more throughput in RFID and backscatter links

Gen 2 modulation schemes for RFID tags operate well below theoretical limits of throughput for backscatter modulation. This paper demonstrates how coding concepts from magnetic and optical recording media can be adapted to boost date rates through the RFID channel. Without sacrificing power consumption, simplicity, or current RF hardware designs, current tag throughputs are shown to increase by at least 50%. These throughput gains are needed by the increased data demands of RFID sensors, RFID-enabled Machine-to-Machine (M2M) communications, and emerging Internet of Things (IoT) applications.
