Abstract
Described are an iterative decoder and method for implementing an iterative decoder which can be used for error correction in data communications. In one implementation, the method includes implementing a first function including a first plurality of Gilbert cells, and implementing a second function including a second plurality of Gilbert cells, where examples of the first and second functions include an equality constraint function and a parity check function. Each of the first plurality of Gilbert cells and the second plurality of Gilbert cells includes n m-input Gilbert multipliers, in which n is an integer greater than (3) and m=(n−1).
