Abstract: The present invention describes an orthogonal frequency-division multiplexing, OFDM, transmitter and a method for embedding phase reference symbols into an OFDM symbol. The invention comprises a single-carrier pre-processing unit arranged to receive phase reference symbols and provide pre-processed phase reference samples as output and an OFDM modulator arranged to receive data symbols and the pre-processed phase reference samples as input and map the data symbols to sub-carriers and embed the single-carrier samples into a frequency sub-band of the OFDM symbol. While the invention particularly relates to an OFDM communication system, it should be noted that it could be applicable to any type of multicarrier communication system.

Abstract: The teachings herein disclose a receiving node and a related method for determining a channel estimate of a radio channel in a receiving node of a radio communication system. The method comprises calculating a matched filter channel estimate based on a known reference signal and a received reference signal in a frequency domain, transforming the matched filter channel estimate into an over-sampled transform domain channel estimate, applying a window to the over-sampled transform domain channel estimate to achieve a windowed transform domain channel estimate, transforming the windowed transform domain channel estimate into a frequency domain channel estimate, and compensating for a bias in the over-sampled frequency domain channel estimate based on a digital sinc function.

Abstract: The embodiments herein relate to a method in a first network node (301) for handling Automatic Gain Control, AGC, scaling and Transmit Power Control, TPC, scaling of a signal received from a second network node (305). The first network node AGC compensates the signal for any AGC scaling changes. The AGC compensating the signal results in an AGC compensated signal comprising a constant AGC scaling. The first network node detects a TPC scaling change of the signal. The detection is based on the signal after the TPC scaling change and based on a predicted channel estimate. The predicted channel estimate is based on the signal before the TPC scaling change. The first network node TPC compensates for the detected TPC scaling change. The TPC compensation results in an AGC and TPC compensated signal comprising the constant AGC scaling and a constant TPC scaling according to the detected TPC scaling change.

Abstract: A miniaturized plasma source includes a stripline split-ring resonator. The split-ring resonator is sandwiched between two dielectric substrates and two metal ground planes. In order to make the plasma accessible from the outside of the ground planes, a hole is made through the gap between the ends of the split ring. The two ground planes act as an electromagnetic shield, protecting the split-ring resonator from electromagnetic interference due to changes in the electric or dielectric environment surrounding it. The miniaturized plasma source is particularly useful in optogalvanic spectroscopy applications.

Abstract: A method for noise rise estimation in a wireless communication system comprises measuring of received total wideband power a plurality of times and computing an estimate of a noise floor measure based on a number of the measured received total wideband powers. An interference whitening is performed based on one of GRAKE, GRAKE?and chip equalizer. A useful signal power for the first user after interference whitening is determined. A first user noise floor compensation factor is derived based on combining weights for the first user used in the interference whitening. A code power to interference ratio measure for said first user is obtained. A noise rise measure is calculated, based at least on the useful signal power for the first user after interference whitening, the first user noise floor compensation factor, the code power to interference ratio measure for the first user and the noise floor measure.
