2 results about "Distributed source coding" patented technology

Systems and methods of employing distributed source coding in power-domain and / or code-domain uplink NOMA schemes are provided. In the provided systems and methods, the scheduling and the parameters of a joint source-channel coding and multiple access framework may be jointly optimized.

The application discloses a multi-base station cooperative communication optimization method based on reinforcement learning and belongs to the technical field of wireless communication processing; through 7-2 layer function segmentation, beamforming is sunk to a remote unit, and local beamforming weight is calculated by using global precoding auxiliary information fed back by a central unit at a previous moment, so that high-dimensional antenna signals are reduced to low-dimensional user data streams; a joint quantizer based on Wyner-Ziv distributed source coding is adopted, spatial correlation between data streams of different remote units is used for compression, and a compression codebook and a global precoding matrix are jointly designed, so that mutual information between a quantization noise covariance matrix and a user interference channel is minimized; a multi-user channel matrix is reconstructed based on compressed data streams, and a reinforcement learning intelligent agent is introduced, an adaptive cooperative precoding strategy is output through intelligent decision-making, and differential pulse code modulation and adaptive quantization are adopted to efficiently feed back the global precoding matrix.
