In this paper, we focus on the delay constrained scheduling problem for wireless link communication under the practical concerns, such as the practical power consumption of transmitter and energy used for channel estimation. In particular, we target to design an energy-efficient scheduling policy that minimizes the total energy expenditure while satisfying the deadline constraint based on knowledge...
Coherent OFDM detection requires accurate channel state information (CSI). Mobile radio channels are both time and frequency dispersive, especially at high vehicular speeds, which makes channel estimation a challenging problem in system design. Conventional preamble-based and pilot-aided channel estimation require numerous reference signals, which significantly compromises the system throughput. This...
