Receiving device, receiving method, and program

A receiving method of a receiving device that receives a single carrier signal, comprising:

• performing a correlating process for a received reference signal in which said single carrier signal was transformed from a time domain signal into a frequency domain signal and a pre-stored reference signal so as to obtain estimated channel values;
• computing compensation coefficients corresponding to residual multipath interferences based on a bit likelihood;
• computing equalized weights based on said estimated channel values and said compensation coefficients;
• generating an equalized signal by an equalizing process for the received signal that is the frequency domain signal based on said equalized weights;
• generating residual multipath interference replicas based on frequency domain symbol replicas, said estimated channel values, and said equalized weights;
• and
• subtracting said residual multipath interference replicas, which are the frequency domain signals, from said equalized signal, which is the frequency domain signal.

A non-transitory recording medium that records a program that causes a signal processing section of a receiving device that receives a single carrier signal to operate, comprising the processes of:

• performing a correlating process for a received reference signal in which said single carrier signal was transformed from a time domain signal into a frequency domain signal and a pre-stored reference signal so as to obtain estimated channel values;
• computing compensation coefficients corresponding to residual multipath interferences based on a bit likelihood;
• computing equalized weights based on said estimated channel values and said compensation coefficients;
• generating an equalized signal by an equalizing process for the received signal that is the frequency domain signal based on said equalized weights;
• generating residual multipath interference replicas based on frequency domain symbol replicas, said estimated channel values, and said equalized weights;
• and
• subtracting said residual multipath interference replicas, which are the frequency domain signals, from said equalized signal, which is the frequency domain signal.
