WebAdaptive exponential min sum algorithm (AEMSA) demonstrate a noticeable improvement over the normalized min Sum algorithm (NMSA) and the BP algorithm in high signal to noise ratio (SNR). The belief propagation (BP) algorithm for low density parity check (LDPC) codes has proven to have excellent performance and is close to the Shannon limit. WebThe algorithm works as follows: Divide the array into two equal subarrays. Recursively calculate the maximum subarray sum for the left subarray, Recursively calculate the maximum subarray sum for the right subarray, Find the maximum subarray sum that crosses the middle element. Return the maximum of the above three sums. http://vision.psych.umn.edu/users/schrater/schrater_lab/courses/AI2/SumProd.pdf theodor lessing tod
