It outlines the basic principles of solar electricity, solar water heating, wind power, micro-hydro, biomass and heat pumps and their application in urban and rural environments.Echo cancellation in voice communication is a process of removing the echo to improve the clarity and quality of the voice signals.

In our thesis we mainly focused on the acoustic echo. Echo suppression and cancellation methods are commonly called acoustic echo suppression (AES) and acoustic echo cancellation (AEC), and more rarely line echo cancellation (LEC).

Speech enhancement is a classical problem in signal processing, yet still largely unsolved. Two of the conventional approaches for solving this problem are linear filtering, like the classical Wiener filter, and subspace methods.

The acoustic echo canceller chip has been fabricated and veri ed for func-tionality, throughput, and power consumption.

Study on Bilinear Scheme and Application to Three-dimensional Convective Equation (Itaru Hataue and Yosuke Matsuda). In the thesis, we propose to use different approaches to perform acoustic echo cancellation.

In addition, we exploit the idea of blind source separation (BSS) which can estimate source signals using only information about their mixtures observed in each -Application to Acoustic Echo Cancellation () () ().
