Detecting transmissions using geometric transformations in soft bit decoding

An apparatus for reception of data in a wireless communication system, the apparatus comprising at least one processor;

• and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus to:
• determine in accordance with a modulation scheme a candidate set of soft bit blocks representing at least part of the data, the candidate set of soft bit blocks representing a set of constellation points in a modulation constellation of the modulation scheme, wherein an application of each geometric transformation operation of a set of geometric transformation operations to a corresponding subset of the set of constellation points or to the set of constellation points preserves the shape of the modulation constellation but results in data being represented differently;
• for each geometric transformation operation of the set of geometric transformation operations, modify according to the geometric transformation operation corresponding soft bit blocks of the candidate set of soft bit blocks resulting in another candidate set of soft bit blocks;
• select from the candidate sets of soft bit blocks the candidate set of soft bit blocks that represents the at least part of the data.
