20110305267 | Precoder for a Communication System and Methods Used in Said Communication System - The present invention relates to a precoder for a communication system arranged to provide transmission blocks for transmission over a transmission channel based on inputted symbol blocks. The precoder is arranged to pre-distort each symbol block based on an estimate of the characteristics of the transmission channel so that the corresponding transmission block appears to be undistorted after transmission over the transmission channel. In accordance therewith, the precoder is arranged to apply Tomlinson-Harashima precoding on a sum of a first measure corresponding to predistortion so as to remove intrasymbol interference and a second measure corresponding to predistortion so as to remove intersymbol interference. The present invention further relates to a method for providing transmission blocks for transmission over a transmission channel in a communication system. | 12-15-2011 |

20150180693 | Baseband Processing of TDD Signals - Transceiver device and method therein, for baseband processing of signals associated with TDD communication over wire lines. The method involves use of a single burst I/O N-point complex FFT kernel for baseband processing of receive and transmit signal blocks, where the processing involves simultaneously performing a respective FFT or IFFT of two N-sample signal blocks. | 06-25-2015 |
20150229464 | Baseband Processing of TDD Signals - Transceiver and method therein, for baseband processing of signals associated with TDD communication over wire lines. The method involves use of a single streaming I/O N/2-point complex FFT kernel for baseband processing of N-sample transmit and receive signal blocks. The processing comprises converting the N-sample signal blocks into intermediate N/2-point signals. | 08-13-2015 |

20160034421 | DIGITAL PRE-DISTORTION AND POST-DISTORTION BASED ON SEGMENTWISE PIECEWISE POLYNOMIAL APPROXIMATION - A nonlinear distorter is configured to mitigate nonlinearity from a nonlinear component of a nonlinear system. The nonlinear distorter operates to model the nonlinearity as a function of a piecewise polynomial approximation applied to segments of a nonlinear function of the nonlinearity. The nonlinear distorter generates a model output that decreases the nonlinearity of the nonlinear component. | 02-04-2016 |
