20080240265 | SYSTEM HAVING AN OFDM CHANNEL ESTIMATOR - A method for an operating system including a channel estimation for OFDM systems in a receiver is disclosed. One embodiment provides information indicative of multiple transmitter signals reception characteristics of signals received from multiple transmitters. Then, channel estimation is performed dependent on the information. | 10-02-2008 |
20100040154 | CHANNEL ESTIMATION - A method of channel estimation and a channel estimator for a multiple carrier radio transmission system is described. The method comprises receiving a signal comprising a symbol-carrier matrix, the symbol-carrier matrix comprising a pre-determined pattern of pilot symbols, and determining first channel estimates at pilot symbol positions of the pilot symbols in the symbol-carrier matrix. The method further comprises determining second channel estimates at intermediate positions of the symbol-carrier matrix, wherein the intermediate positions are separated from the pilot symbol positions of the pilot symbols by positions associated with non-determined channel estimates and determining third channel estimates at further positions of the symbol-carrier matrix. | 02-18-2010 |
20140140194 | METHOD FOR GENERATING AN OFDM DATA SIGNAL - An OFDM signal generator includes a time domain data signal generator configured to generate a time domain data signal, a partial signal generator configured to generate a plurality of partial signals based on a tail section of the time domain data signal, and a circuit element configured to form a difference between or a sum of the time domain data signal and the plurality of partial signals. | 05-22-2014 |
20140355626 | METHODS AND DEVICES FOR PROCESSING A DATA FRAME - A method including processing a data frame, the data frame having a predetermined frame size and including at least one data symbol configured to form a plurality of sub-carriers in the frequency domain, wherein each of the at least one data symbol comprises a user data portion and a guard interval portion, wherein each of the at least one data symbol includes a plurality of sub-symbols, and wherein at least one of the following parameters is variable during the processing: a size of the guard interval portion, a size of the user data portion, a size of the at least one data symbol, a number of data symbols the data frame comprises, a content of the guard interval portion, and a configuration of the sub-symbol boundaries. | 12-04-2014 |

20150271687 | METHOD AND DEVICE FOR INTERFERER SCHEDULING DETECTION AND NOISE AND INTERFERER PARAMETER ESTIMATION - A method for estimating noise and interferer parameters includes receiving a signal comprising a noise and interference signal contribution. Noise and interference power samples are generated based on the signal. The noise and interference power samples are quantized into quantization levels. The occurrences of noise and interference power samples are accumulated for each quantization level during an observation period. Noise and interferer parameters are estimated based on the number of occurrences of noise and interference power samples per quantization level during the observation period. | 09-24-2015 |
20160095136 | NETWORK ASSISTED PARAMETER ESTIMATION IN THE PRESENCE OF INTER-CELL INTERFERENCE - Embodiments provide improved interference classification and parameter estimation at a User Equipment (UE) that uses received scheduling information associated with interfering cells from a network node together with parameters associated with interfering cells generated locally to the UE to generate an interference mapping data set that may be used to adjust subsequent interference classification and parameter estimation processing in the UE. | 03-31-2016 |
