Channel coding is a vital unit of any communications system. Future wireless systems are necessary to be equipped with high performance codes having low complexity encoder and decoder design. The requirements of these systems range from providing high throughput, operating in highly reliable scenarios, to working with short and long information messages, low and high code rates. To obtain maximum coding gain in wireless communication systems, Turbo codes and Polar Codes are used as error correcting codes. Satellite communication and 4G/5G services widely use these codes. These codes are found to approach Shannon capacity performance. Two recursive systematic convolution encoders separated by an interleaver are used to build a turbo encoder. Polar Codes are constructed on the concept of channel polarization. This work focusses on the Bit Error Rate evaluation and analysis of the codes for varying block lengths and code rates
