The observed signals that usually play the role of error references for adaptive echo cancellers and channel equalizers in data communications are basically composed by data plus a residual error. The goal of such systems is to eliminate those errors to enhance the present data. However, in some systems, depending on the convergence stage, the presence of data in the ...

In this paper, we propose an equivalent model for subband adaptive systems, in order to analyze the performance of the system. Using the proposed model, we obtain a new interpretation of the system, and show theoretical equations of the optimum adaptive digital filter (ADF) coefficients and the least mean squared error (LMSE). From these equations, we also derive the theoretical ...

A multi-echo-path echo canceller (MEP-EC) is described, which works well together with a microphone selection unit. Echo cancellation performance was measured in a teleconference room, and 28-dB echo cancellation was obtained. The echo cancellers were implemented in an acoustic echo canceller system, ACII, for teleconferencing.<>

In discrete multitone (DMT) transceivers an intelligent guard time sequence, called a cyclic prefix (CP), is inserted between symbols to ensure that samples from one symbol do not interfere with the samples of another symbol. The length of the CP is determined by the length of the impulse response of the effective physical channel. Using a long CP reduces the ...

On-frequency repeaters, whose input and output signals are the same frequency, often experience radiated coupling between the input and output antennas which causes echoes to be transmitted. In addition, the repeater will oscillate if the forward gain of the repeater is higher than the isolation between antennas. This paper proposes a method of estimating and compensating for the effects of ...
