On adaptive reception for Dynamic Lattice Multicarrier Transmission system with varying speed receiver

In this paper, an adaptive reception scheme for Dynamic Lattice Multicarrier Transmission (DLMT) system with varying speed receiver is proposed. Theoretical analyses show that there is a timing offset between the prototype pulses of the proposed adaptive receiver and the traditional projection receiver. Meanwhile, the timing offset and prototype pulse should be adapted to the non-stationary doubly dispersive (NSDD) channel introduced by the user mobility. The closed-form timing offset expression of the proposed adaptive receiver over NSDD channel is derived. Simulation results show that the prototype pulse of the proposed adaptive receiver matches the user mobility with a greater dynamic range when compared with the iterative receiver and the Max-SINR receiver designed for stationary wireless channel. Meanwhile, the Signal-to-Interference-plus-Noise Ratio (SINR) performance of the proposed adaptive receiver outperforms traditional projection receiver, iterative receiver and the Max-SINR receiver.
