摘要： A method is disclosed that includes measuring, during a measurement period, values corresponding to noise and interference signals received from a channel. The measurement period coincides with a period when no signal is transmitted on the channel. The method also includes determining one or more thresholds based upon the measured values. Second signals that correspond to a message are received on the channel. The message includes an indicator having a number of possible states. A value is determined corresponding to the indicator based upon the second signals. One of the possible states is assigned to the indicator of the received message based upon the one or more thresholds and the determined value.

摘要： The invention relates to a method and arrangement for enhancing a search through a trellis in a detector (220) that is arranged at each stage of the trellis to select a certain set of state indexes of the stage for continuation. The detector (220) is arranged, when each stage of the trellis is calculated, to define more than one unequal threshold value for the values of the state indexes, each threshold value defining one state index group, to calculate for each state index a path metric, to arrange the calculated state indexes into different groups by comparing the path metric value of the state index with the threshold values. Further the detector selects from the groups a certain number of state indexes for continuation in such a manner that starting from the group comprising the highest state indexes, entire groups are selected for continuation until the next entire group does not fit in. From this group only randomly selected state indexes are selected until a given number is collected.

摘要： According to an example embodiment, an example technique may include encoding a dataword into a codeword, mapping the codeword to a mapped word, generating a waveform corresponding to the mapped word, and transmitting the generated waveform via a wireless channel. A dynamic range cost function (such as, for example, peak-to-average power ratio (PAPR)) of the waveform corresponding to the mapped word may be less than a dynamic range cost function of a waveform corresponding to the codeword. In this manner, dynamic range of signals may be decreased, for example.

摘要： Disclosed is an interpolation procedure for channel estimation that is based on minimum mean-squared error (MMSE) estimates over comb-type pilot signals. The time domain (TD) interpolated channel estimation suppresses, by the use of an advanced noise suppression scheme, the noise jitter that spreads over all or substantially all of the bandwidth of interest. The original channel estimates in the frequency domain (FD) are transformed into the TD by an IFFT function, where in one embodiment a predefined threshold on actual power or accumulative power is used to minimize the noisejitter over the bandwidth. In a further embodiment the channel estimates in the FD are transformed into the TD and the noise jitter is suppressed by preserving the channel estimates at the actual tap delays and setting the others to zeroes. In either embodiment the noise suppressed channel estimates are then transformed into the FD for FD equalization.
