摘要： The present disclosure relates to a reception device, a method, and a program, which realize a non-linear distortion compensation of a hard decision at a low cost. A hard decision unit is composed of a slicer (Slicer) . The hard decision unit inputs average amplitude (1) to (n) and average phase gaps (1) to (n) of each ring from an amplitude/phase gap averaging unit, corrects at least one of amplitude and phase threshold processings, and performs a hard decision on a result of filtering with a feed-forward filter by using the corrected amplitude and phase-targeted threshold processings. The hard decision unit outputs a hard decision result S' k to an error calculation unit. The present disclosure can be applied to, for example, a reception device that receives a signal of ASPK satellite digital television broadcasting.

摘要： A wireless terminal (1) is configured to, (a) when transmitting uplink control information in a first subframe of a radio frame, determine the number of coded symbols (Q') for the uplink control information by a first calculation method, and (b) when transmitting the uplink control information in a second subframe of the radio frame, determine the number of the coded symbols (Q') for the uplink control information by a second calculation method different from the first calculation method. This can contribute, for example, to adjusting redundancy of coded uplink control information (UCI) bits on a per-subframe basis.
