Abstract:
1. A method for use in a processor for deciding a transmitted signal corresponding to a received signal, the transmitted signal comprising a plurality of sub-transmitted signals, the method comprising the steps of: selecting at least one of the sub-transmitted signals as a first reference signal group by a selection module of the processor, the first reference signal group having a plurality of first candidate signal values, and each of the first candidate signal values forming a first candidate geometric space respectively; deriving a plurality of first projection signals by projecting the received signal onto each of the first candidate geometric spaces respectively by a projection module of the processor; deriving a plurality of first quantization signals by quantizing each of the first projection signals in the corresponding first candidate geometric space by a quantization module of the processor, a first projection distance existing between each of the first quantization signals and the corresponding first projection signal; and deciding the transmitted signal by using the first quantization signal that corresponds to the shortest first projection distance and the first candidate signal value that corresponds to the shortest first projection distance by a decision module of the processor.
