Polar decoder with LLR-domain computation of f-function and g-function
Polar decoder with LLR-domain computation of f-function and g-function
A polar decoder kernal is described. The polar decoder kernal includes a processing unit having: at least one input configured to receive at least one input Logarithmic Likelihood Ratio, LLR; a logic circuit configured to manipulate the at least one input LLR; and at least one output configured to output the manipulated at least one LLR. The logic circuit of the processing unit includes only a single two-input adder to manipulate the at least one input LLR, and the input LLR and manipulated LLR are in a format of a fixed-point number representation that comprises a two's complement binary number and an additional sign bit.

Abstract
A polar decoder kernal is described. The polar decoder kernal includes a processing unit having: at least one input configured to receive at least one input Logarithmic Likelihood Ratio, LLR; a logic circuit configured to manipulate the at least one input LLR; and at least one output configured to output the manipulated at least one LLR. The logic circuit of the processing unit includes only a single two-input adder to manipulate the at least one input LLR, and the input LLR and manipulated LLR are in a format of a fixed-point number representation that comprises a two's complement binary number and an additional sign bit.
