Abstract :

Since parameters such as bandwidth, power, and cost have an undeniable essential role in the performance of communication systems, designing new methods to improve the performance of systems, including designing suitable methods for demodulation and decoding, has always been considered by researchers. Utilizing millimeter-wave (mm-wave) frequency bands and, by nature, multi-gigabit per-second wireless communications pose challenges in implementing an analog-to-digital converter (ADC) to achieve high data rates in terms of extremely high power consumption. This paper proposes a joint ADC-less scheme for implementing the analog demodulation and decoding of extended (8, 4, 4) Hamming codes. Our proposed scheme is based on amplitude threshold estimation and phase detection and subjoins two decoding and demodulation blocks.
