Paper Title
Improved Performance of Hard Decision Decoding Using Turbo Product Codes

In this paper discuss the decoding algorithm with low complexity low and reliable to detect errors in communication system using hard decision decoding of multidimensional turbo product codes. In this paper we also try to come nearer to the performance of soft decision decoding, the performance comparison of soft decision decoding is 2db better than the hard decision decoding. In this paper we achieve the same performance with low complexity by using hard decision decoding. The bit flip algorithms and multilevel dimensions are used in process of iteration.
