Title: Chang Wen Chen: Innovator in Video Multicast Technologies
Introduction
Chang Wen Chen is a prominent inventor based in East Amherst, NY (US). He has made significant contributions to the field of video multicast technologies, holding a total of 5 patents. His work primarily focuses on enhancing communication systems through innovative methods.
Latest Patents
One of his latest patents is titled "Spatial scalable video multicast for heterogeneous MIMO systems." This invention describes a multiplexed space-time block coding (M-STBC) scheme that enables the transmission of a single multicast transmission in a heterogeneous MIMO environment. In this system, receivers with fewer antennas can access a lower resolution version of the multicast transmission, while those with more antennas can receive a higher resolution version. This innovative approach allows for both spatial multiplexing and diversity modes in multicast transmissions.
Another notable patent is "Fast decoding based on ZigZag deconvolution for random projection code." In this invention, multi-level symbols generated by applying a Random Projection Code (RPC) to a source bit sequence are transmitted through a noisy channel. The received symbols are represented in a bipartite graph, where a decoder utilizes ZigZag deconvolution to generate messages for iterative belief propagation, ultimately decoding the source bit sequence from the received symbols.
