abstract = "This chapter presents a channel tracking and equalization solution suitable for unmanned aerial vehicle (UAV) communications. Particularly and since the UAV channel is considered to be doubly-selective, we employ single-carrier modulations combined with frequency-domain equalization (SC-FDE). Accordingly, the equalization procedure is dealt by a low-complexity iterative frequency-domain equalizer based on the iterative block decision-feedback equalization (IB-DFE) and the tracking procedure is conducted by an extended Kalman filter (EKF). These systems are very efficient since they allow a very low density of training symbols, even for fast-varying channels. Additionally, only two consecutive training symbols are required to initialize the tracking procedure, thus ensuring low latency together with reduced channel estimation overheads.",
