Abstract: A method of compensating phase error of a received signal is disclosed. The signal comprises a symbol set comprising a plurality of symbols of a first type having an N-Quadrature Amplitude Modulation, N-QAM, signal configuration, where N is an integer larger than 4, and at least one symbol of a second type having an Amplitude and Phase-Shift Keying, A-PSK, signal configuration, wherein both the symbols of the first type and of the second type carries data and wherein the symbols of the second type also are arranged as pilot symbols for determination of phase rotation determination. A receiver and transmitter, as well as a communication system, employing the symbol set are disclosed.

Abstract: A device and a method for deviation determination for use during transfer of a phase shift modulated information-carrying signal between a transmitter and a receiver. The deviation determination is based on the presence of phase-linear segments, i.e., parts of sequences of phase changes that have the same phase change. Segments having three or more consecutive phase changes of the same value are extracted. An identification of the filtered-out segments is performed in order to determine which nominal phase-linear sequences the segments belong to. After this, the deviation and possibly a correction signal can be determined.

Abstract: A method of demodulating digital data using M'ary QAM has been disclosed, comprising the steps of detecting a complex symbol vector D, establishing within which reference symbol boundaries the detected symbol vector D falls, the given reference symbol boundaries being associated with a complex reference vector R. Quadrature components (E_I and E_Q) of an error vector (E) constituting the difference between the detected vector D and the associated reference vector R are found and an error control signal (E') as feed back signal in the demodulation stage is approximated. The influence of thermal noise in the receiver stage has been limited by a weighting and/or by noise balancing.

Abstract: Method of communicating digital data in which frames (8) are transmitted cyclically whereby a first number of symbols is transmitted according to a first keying mode (II) using a first constellation, and a second number of symbols is transmitted according to a second keying mode (L) using a second constellation. The first and second keying modes (H, L) are used at predetermined positions in the frame, whereby both the symbols according to the first and second keying mode carry information under at least an operative traffic phase.

Abstract: A device and a method for deviation detection for use during transfer of a phase shift modulated information-carrying signal between a transmitter and a receiver. The deviation detector makes use of the presence of phase-linear segments, i.e. parts of sequences of phase changes with consecutively the same phase change. The deviation detector extracts segments consisting of three or more consecutive phase changes with determined same phase change. An identification of the filtered-out segments is performed in order to determine which nominal phase-linear sequences the segments belong to. After this, the deviation and possibly a correction signal can be calculated.

Abstract: The present invention use the properties of a TDD-transmission on a general mixer in such a manner that in the transmit mode a first RF signal is amplified in the mixer with an amplification factor greater than, or equal to, or less than one, and in the receive mode the received RF signal is mixed with a second RF signal.
