Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of enhanced decoding for polarization code. The method includes determining a likelihood sequence associated with a signal sequence received from a second device via a communication channel between the second device and the first device; generating a set of candidate sequences of the signal by processing the likelihood sequence with a first operation; determining a reference sequence by processing the likelihood sequence with a second operation different from the first operation; and determining a target sequence of the signal from the set of candidate sequences at least partially based on the reference sequence. In this way, the decoding at receiver side can be enhanced to less rely on CRC during decoding. This could dramatically improve the overall performance of the channel.

Abstract: An apparatus comprising means for receiving information indicative of a relative placement of an object and a camera; determining, in dependence on the information, whether a condition associated with relative placement of the object and the camera is satisfied; and causing display of an indication of at least one detected characteristic of the object if the condition is satisfied.

Abstract: A method for encoding a sequence of control information bits comprising: generating a sequence of error detection bits based on the sequence of control information bits; generating a sequence of error correction bits based on the sequence of control information bits; and distributing the sequence of error detection bits and the sequence of error correction bits between the sequence of control information bits to form a combined sequence of bits, such that the bit order of the combined sequence of bits following the distribution enables an error detection check to be performed before or after a first error correction check bit.

Abstract: A method including determining a cyclic redundancy check (CRC) generator sequence defining a one to one mapping between a sequence of control information values and cyclic redundancy check (CRC) sequence values; and determining a combined sequence, the combined sequence formed by distributing the cyclic redundancy check (CRC) value sequence within the sequence of control information values, wherein the distributing the cyclic redundancy check (CRC) value sequence within the sequence of control information values is based on a selected part of the cyclic redundancy check (CRC) generator sequence.
