Title:
MULTICARRIER COMMUNICATION SYSTEM FOR DOUBLY SELECTIVE CHANNELS USING VIRTUAL TRAJECTORIES RECEIVER
Document Type and Number:
WIPO Patent Application WO/2017/037623
Kind Code:
A3
Abstract:
A modified orthogonal frequency-division multiplexing (OFDM) communication system based on virtual decomposition of the channel is proposed. The system is fully compatible with standard OFDM transmitters and maintains several blocks of standard OFDM receivers. The proposed approach achieves also incoherent reception of multicarrier signals even with a simple autocovariance DPSK detector. This novel system substantially surpasses the performance of current approaches while requiring low computational complexity. Two preferred embodiments are described; one with coherent reception using pilot signals, and the second with incoherent receiver of differentially encoded signals.
