A method for equalizing and decoding an error-protected data signal transmitted via a radio channel is described. According to the method, an equalized data signal is calculated at the receiving end in a demodulator with a first channel estimator. The equalized data signal is decoded by a decoder to determine a decoded output signal. The equalized data signal is transmitted to a second channel estimator, which repeatedly detects second channel parameters of the radio channel. The parameters are transmitted to the decoder which uses them as calculation parameters during decoding.

A device for holding an object, and an assembly for holding and rotating an object. The device includes a base, a series of posts, each of which is equidistant from a center point of reference and further pivotably holds a follower rotationally linked to all other followers. Each follower has a gripping portion dimensioned to hold an object. An actuator serves to displace the followers radially about the post holding it creating a motion that causes the gripping portions to move either towards or away from the center reference point, dependent upon the displacement of the actuator. As all followers are rotationally linked, each follower of the device rotates to a substantially equal degree.

摘要:
A method for estimating channel parameters of radio channels of a W-CDMA mobile radio system, for example in accordance with the UMTS standard includes transmitting sequences of known symbols between unknown data symbols by a base station. The channel estimation is carried out by a comparison of the received sequences with the known symbols, and the result of the comparison is integrated over a sequence of known symbols.

摘要:
To achieve an improved disparate error protection in the transmission of coded symbols of an information stream, the information stream is supplied to a multiplicity of coding branches for coding, and is supplied in parallel, to a puncturing and multiplexing unit. Symbols of different quality classes are fed into each coding branch using a demultiplexer. An interleaver follows at least one demultiplexer for generating error protection for the filtered symbols. The symbols, which may possibly be interleaved, are coded in each coding branch and are supplied to the puncturing and multiplexing unit. The puncturing and multiplexing unit sets a predetermined coding rate.
摘要:
A light emitting device includes a light source that emits first light in response to an electrical signal, and a fluorescent layer positioned over the light source. The fluorescent layer includes a first fluorescent material which radiates second light and a second fluorescent material which radiates third light. In one embodiment, the second fluorescent material contains europium activated calcium sulfide. In another embodiment, the second fluorescent material contains europium activated nitrido-silicate. In some embodiments, the device includes a light propagation medium which transmits the first, second, and third light as composite output.
