Introduction to Error Control Coding ECE Seminar Idea:

The transmitted signal cannot be the original transmitted message signal which is received and the receiver channel. Due to noise the binary pulse train of the digital signal gets disturbed which reduces the quality of the output. To overcome this various methods are used and it requires additional equipment to be installed transmitter and the receiver units which can eliminate the noise occurred in the signal. In this paper we pose a error coding technique which can identify the error signal and there by reduces the signal to noise ratio occurring in the signal. We will see how this algorithm works and how low bit error rate is achieved by using this coding method.

Brief on the error coding technique:

If noise is entered into the digital it change the binary pulse which makes the zeros to appear as one or ones may be transmitted as zeroes which reduces the quality at the receiver output. The theoretical analysis of this method is possible by using a Shannon’s channel theorem where the convolution codes are specified among the three parameters. Here each input bit is coded into 3 output bits and the constraint length of the code is 2.

We use n modulo 2 to represent the output bits and we connect memory registers to the adders by using generators polynomial. So each input bit generates three output polynomials and we get the required output bit by adding the obtained three obtained polynomials. Each polynomial will have its unique error protection quality code be they differ from the other polynomial.

Conclusions:

This is most efficient technique for reducing the bit error rate occurring in the signal than other conventional methods. By using this method we can reduce the error value for a fixed bit error rate which reduces the transmitted power sine on the antenna.
