Channel estimation and secure data transmission using hybrid particle swarm optimisation–gray wolf optimisation‐leaky least‐Mean‐Square and affine elliptic curves cryptography algorithm in MU‐multi‐input multi‐output orthogonal frequency division multiplexing system

Summary In a huge multi‐input multi‐output orthogonal frequency divisions multiplexing (MIMO‐OFDM), an exact Channel State Information (CSI) is required to understand the system performance, which includes high spectrum together with energy efficiency. Using the OFDM, substantial numbers of pilots a...
