An apparatus is provided for suppressing an echo signal included in a measured signal corresponding to a measured sound. In the apparatus, the measured signal and a reference signal in a time domain are transformed into a frequency domain, and calculated for obtaining each value of a ratio and a correlation between the measured signal and the reference signal in the frequency domain. With executing a comparison of the values of the ratio and the correlation, a coefficient is derived, where a product of the coefficient and the measured sound in the frequency domain gives an estimated value of the echo signal. The echo in the measured signal is suppressed with subtracting the estimation of the echo signal from the measured signal, respectively in the frequency domain.

The present invention relates to the field of photovoltaic systems with solar cell (s) or modules having insolation differences or mismatch. Each solar module is formed by placing a large number of solar cells in series. The PV system is then formed by placing a number of solar modules in series in a string and sometimes by placing multiple strings of series-connected solar modules in parallel, depending on the desired output voltage and power range of the PV system. In practical cases, differences will exist between output powers of the solar cells in the various modules, e.g. due to (part of) the modules being temporarily shaded, pollution on one or more solar cells, or even spread in solar-cell behaviour that may become worse during aging. Due to the current-source-type behaviour of solar cells and their series connection these differences will lead to a relatively large drop in output power coming from the PV system. This invention addresses this problem by adding DC-DC converters (803) on a single or multiple solar-cell level that source or sink difference currents thereby increasing the output power of the complete PV system. In embodiments, the efficiency of photovoltaic systems with solar cell (s) or modules is improved by compensating for output-power loss caused by insolation difference and mismatch.

When a transmission device transmits a broadcast service signal using a radio signal, the transmission device determines whether there is a moving body that is moving at high speed toward or away from the transmission device, and calculates the amount of Doppler shift of a radio frequency due to high speed movement based on the movement speed of the moving body when there is such a high-speed moving body. Moreover, the transmission device shifts the frequency of the radio signal for transmitting the broadcast service signal by the Doppler shift amount in the opposite direction of Doppler shift direction. By doing so, it is possible for a moving terminal to receive the broadcast service signal from the original radio frequency regardless of Doppler shifting.
