说明：  pq法的谐波检测，谐波源是三相全桥整流电路(Pq method of harmonic detection, harmonic source is a three-phase full-bridge rectifier circuit)

4 16 64 QAM plots for simulated and theoretical results for OFDM system under a standard Rayleigh channel

Detecting faces or in general, objects, inside gray-level images is still a hard topic for new researches and students all over the world. It s certainly not your fault. Many researches who do not have access to the right resources, struggle for weeks and months before they understand how to manage their project.
