摘要:
The proposed iterative method concurrently calculates maximum likelihood estimated values for the channel coefficients (h0, . . . , hL; θh) and the DC offset (d; θd) on the basis of a training sequence (TSC) in a TDMA mobile communications system. The SAGE algorithm leads to two recursion formulae, by means of which the iterative calculation of estimated values for the channel coefficients (h0, . . . , hL; θh) and for the DC offset (d; θd) is provided.

摘要:
In a method for correlative estimation of a mobile radio channel on the basis of a training sequence (TS) which is transmitted via the mobile radio channel, a sequence of P received symbols is correlated with a subsequence of length P of the training sequence, in order to calculate a first estimated channel coefficient (ĥ0(1)). Furthermore, the same sequence of P received symbols is correlated with at least some of the subsequences of the training sequence (TS) shifted through ±1, ±2, . . . , ±(Lt−1) symbol positions, in order to calculate a number of further estimated channel coefficients (ĥ±1(1),ĥ±2(1), . . . ,ĥ±(Lt−1)(1)).

A device for scaling and quantization of digital soft output values (sk) from an equalizer has a control loop for controlling a statistical parameter (θ) for the scaled and quantized soft output values (sD,k), which contains a calculation unit (4) for calculation of the statistical parameter (θ), and a control unit (5) for calculation of a scaling factor (c) for scaling the soft output values (sk) from the equalizer on the basis of the statistical parameter (θ).
摘要:
In order to compensate for a frequency offset or a change in the phase of the transmission channel over time during mobile radio transmission of data symbols, the data symbols are transmitted by way of carrier-frequency, modulated data bursts. Sample values of the received signal, which are known in advance and correspond to first and second symbols, are evaluated in order to estimate the frequency offset or the change in the phase of the transmission channel over time. These first and second symbols are transmitted with a defined phase angle by way of the data burst, and are arranged separated from one another in the data burst. Edge symbols in a data burst are advantageously used as first and second symbols, or as a symbol pair, for estimation.
摘要:
In a method to compensate for a step DC disturbance (1) in a baseband signal in a homodyne radio receiver, the time profile of the step DC disturbance within a burst is determined. In order to produce a step-corrected baseband signal, the determined time profile (2) is then calculated from the digitized baseband signal.
