Embodiment Construction

[0018] Such as figure 1 As shown, a method for designing a receiving end of a 5G communication system based on folding includes the following steps:

[0019] (1) Unified description of the BP problem solution; the BP algorithm based on the symbol set can be expressed by the following two formulas

[0020]

[0021] beta ji (c k ) = ∑ l≠i alpha lj (c k ) (2)

[0022] In the above two formulas, α ij (c k ) represents the symbol c passed from the i-th function node to the j-th variable node k The log likelihood ratio information of , its format is s is the set of all possible vectors and the set of all solutions; F i (s) is a conditional probability function, according to different scenarios, different nodes change; β li (c k ) is the symbol c passed from the lth variable node to the ith function node k information; if the LLR is defined as The formula can also be written as

[0023]

[0024] (2) According to the formula and two kinds of nodes in step (1),...
