In today’s world we are surrounded by world of smart handheld devices like smart phones, tablets, netbooks, and others. These devices are based on advance technologies of multiple-input and multiple-output, Orthogonal Frequency Division Multiplexing (OFDM), and advance data reliability techniques such as forward error corrections. High data rates are among the requirements of these technologies for which turbo and low density parity check codes (LDPC) are widely used in these standards. In order to get high speed, we need multiple and parallel processors for the implementation of such codes. But there exists a collision problem as a consequence of parallel processor. This problem results in increase latency and increase of hardware complexity. In this work an approach for collision problem is presented in which network relaxation technique is used which is based on a fast clique detection. The proposed approach results in high throughput in terms of latency and complexity. Furthermore, the proposed solution is able to solve the collision problem by connecting network optimization for achieving high throughput.
