Embodiments relate to a transmitter (71) for transmitting a signal comprising data symboIs and non-deterministic pilot symbols. The transmitter includes a mapper (712) operable to map one or more non-deterministic bits (u) to a non-deterministic pilot symbol having a pilot symbol phase in a predetermined pilot symbol phase range; and a pilot symbol inserter (115) operable to insert the pilot symbol into a stream of data symbols. Further, embodiments also relate to a corresponding receiver (73) for receiving a stream of data and pilot symbols. The receiver includes a phase estimator (737) operable to estimate a phase of a transmission channel based on a comparison of a received symbol corresponding to a pilot symbol position with a hypothetical pilot symbol, the hypothetical pilot symbol corresponding to one or more hypothetical non-deterministic bits (u) and having a pilot symbol phase in a predetermined pilot symbol phase range. |
