Abstract: Methods for positioning an FFT-window in an OFDM-receiver are disclosed as well as electronic apparatuses and computer program products for performing the methods. The method comprises determining a position of the FFT-window in relation to one or more OFDM-symbols of a received OFDM-signal, using the position of the FFT-window to obtain a first OFDM-symbol from the received OFDM-signal, and applying an FFT to the first OFDM-symbol to produce an FFT-output signal. The method also comprises determining a frequency dependent phase rotation component of the FFT-output signal, and removing the determined frequency dependent phase rotation component from the FFT-output signal to obtain a compensated FFT-output signal. A delay spread estimate is calculated based on at least one of the FFT-output signal and the compensated FFT-output signal, and the position of the FFT-window is adjusted based on at least the determined frequency dependent phase rotation component and the calculated delay spread estimate.

An FFT is applied to the first OFDM-symbol to produce an FFT-output signal. A frequency dependent phase rotation component of the FFT-output signal is determined and removed from the FFT-output signal. A number of zero-crossings of at least one of a real component and an imaginary component of a transfer function of a channel, over which the received OFDM-signal has been transmitted, derived from the FFT-output signal where the frequency dependent phase rotation component has been removed is determined, and a delay spread estimate is calculated based on the determined number of zero-crossings.

Abstract: A frame device adapted to be mounted between a balcony slab and a roof slab (2) located above the former supports wall elements (16, 16?, 16?) for building-in a balcony. The frame device has an upper horizontal sectional element (17), which supports a cover strip (28), which extends parallel thereto and is fastened thereto by holder means (26). The cover strip (28) has a leg (28a), which is inserted into a pocket (27) formed between the holder means (26) and a supporting surface (25) of the sectional element (17). The cover strip (28) is extractable from a retracted position in the pocket (27) to an arbitrarily extracted position so as to provide, when the frame device is mounted between the balcony slab and the roof slab (2), a visual screening off of a gap (S), which is formed between the roof slab (2) and the sectional element (17).

Abstract: A frame device adapted to be mounted between a balcony slab and a roof slab (2) located above the former supports wall elements (16, 16?, 16?) for building-in a balcony. The frame device has an upper horizontal sectional element (17), which supports a second sectional element (31), which is parallel thereto and which is connected to the upper horizontal sectional element pivotally about a pivot axis parallel to the upper horizontal sectional element (17). The second sectional element (31), which is arranged to support a blind device (35) adapted for the balcony, is pivotable relative to the upper horizontal sectional element (17) between an inwardly pivoted position and an outwardly pivoted position for use of the blind device (35).

Abstract: A frame structure, which is adapted to be mounted between a horizontal lower balcony slab (1) and a horizontal upper balcony slab (2) located straight above the former, is arranged to support wall plates (9, 10) for at least partial building-in of the space between the balcony slabs (1, 2). The frame structure has a lower horizontal sectional element (12) arranged to be attached to the lower balcony slab (1), an upper horizontal sectional element (11) arranged to be attached to the upper balcony slab (2), an intermediate horizontal sectional element (13) and two vertical sectional elements (14, 15). The upper and the intermediate horizontal sectional elements (11 and 13) are arranged to support between themselves wall plates (10), such as glass plates, which are horizontally displaceable relative to each other. The vertical sectional elements (14, 15) consist of hollow sectional elements.
