description: The given work is devoted to the problem of learning an echo canceller when standing full duplex exchange. The research set the following goals: Study approaches to modeling hybrid echo and echo cancellers. Develop a mathematical model of a hybrid echo during the transmission of biphase modulated signal. Develop a mathematical model of an echo canceller that will adapt itself on generated data in full duplex mode Develop a hardware implementation of such an echo canceller on an FPGA. The work was fulfilled on the premises of laboratory "Industrial Systems for Streaming Data Processing" of the SPbPU NTI Center, which included collection of DSL equipment, required for research and development. A comparison of different echo-canceller adaptation algorithms was made. A mathematical model was created to model signal in a two-wire line and an echo canceller working with this signal. A series of experiments were carried out with various model parameters. Suitable parameters were found for use in the hardware implementation. As a result, a hardware implementation of the echo canceller was developed, working according to the algorithm from the article by Steven Weinstein. Its technical staging and integration into an existing FPGA project was performed. Designed echo canceller corresponds to the mathematical model and works as part of FPGA-based DSL device.
