“In the realm of secure wireless communication, a new technique called Delay Alignment Modulation (DAM) has emerged to tackle inter-symbol interference (ISI) and enhance security against eavesdropping. This paper delves into the application of DAM in near-field scenarios, demonstrating its potential to achieve ISI-free communication and prevent information leakage. Expert research has established that with DAM, the secrecy rate can be maximized, offering a new direction for secure communication research.”
