Receiver for receiving a combination signal comprising two separate signal portions whose pulses are shifted relative to each other and/or whose carrier oscillations have a phase difference, wherein the receiver is configured to obtain a first series of samples (342, y 1 [k]) using a first sampling, wherein the first sampling is adapted to a symbol phase of the first signal portion; wherein the receiver is configured to obtain a second series of samples (344, y 2 [k]) using a second sampling, wherein the second sampling is adapted to a symbol phase of the second signal portion; wherein the receiver is configured to obtain probabilities p1,m[k] (312; 492) of transmission symbols of the first signal portion and probabilities p2,m[k] (314; 432) of transmission symbols of the second signal portion for a plurality of sampling times (k) based on the first series of samples and the second series of samples; wherein the receiver is configured to determine probabilities p1,m[k] (312; 492) for symbols of the first signal portion based on samples (342, y 1 [k]) of the first sampling and estimated or calculated probabilities p 2,m [k] (314; 432) for symbols of the second signal portion without taking into account inter-symbol interference between transmission symbols of the first signal portion in the samples (342, y 1 [k]) of the first sampling; and wherein the receiver is configured to determine probabilities p2,m[k] (314; 432) for symbols of the second signal portion based on samples (344, y 2 [k]) of the second sampling and estimated or calculated probabilities p 1,m [k] (312; 492) for symbols of the first signal portion without taking into account inter-symbol interference between transmission symbols of the second signal portion in the samples (344, y 2 [k]) of the second sampling. wherein the receiver is configured to obtain a first series of samples (342, y 1 [k]) using a first sampling, wherein the first sampling is adapted to a symbol phase of the first signal portion; wherein the receiver is configured to obtain a second series of samples (344, y 2 [k]) using a second sampling, wherein the second sampling is adapted to a symbol phase of the second signal portion; wherein the receiver is configured to obtain probabilities p1,m[k] (312; 492) of transmission symbols of the first signal portion and probabilities p2,m[k] (314; 432) of transmission symbols of the second signal portion for a plurality of sampling times (k) based on the first series of samples and the second series of samples; wherein the receiver is configured to determine probabilities p1,m[k] (312; 492) for symbols of the first signal portion based on samples (342, y 1 [k]) of the first sampling and estimated or calculated probabilities p 2,m [k] (314; 432) for symbols of the second signal portion without taking into account inter-symbol interference between transmission symbols of the first signal portion in the samples (342, y 1 [k]) of the first sampling; and wherein the receiver is configured to determine probabilities p2,m[k] (314; 432) for symbols of the second signal portion based on samples (344, y 2 [k]) of the second sampling and estimated or calculated probabilities p 1,m [k] (312; 492) for symbols of the first signal portion without taking into account inter-symbol interference between transmission symbols of the second signal portion in the samples (344, y 2 [k]) of the second sampling. <EOS>
