Verilog Implementation of a Turbo Encoder and Decoder with MAP-Based Decoding
Abstract: The most significant achievement in coding theory is the turbo codes which are forward error correction codes developed in 1993. By using two simple recursive systematic convolutional codes in parallel we can achieve near-capacity performance in transmission system which was defined by Shannon-Fano. By using iterative decoding structure near-capacity performance is possible with a relatively easy decoding complexity, using a soft in soft out (SISO) maximum a posteriori (MAP) decoding …

Study of Diagonal Ties and Metal Plate as a Confining Reinforcement for RCC Short Columns
Abstract: Column is a most important structural member in the structural system. Even after the strong column weak beam theory used in the design of the structural member it has been observed that the many times structure collapsed due to the failure of the column. There are many reasons of the column failure but out of that major reason of the failure is ineffective confinement of the column specimen and uneven …
