Performance study on effect of convolutional coding in WCDMA system with different channel condition

WCDMA system is meant for high data rate transmission such as implementation of the third generation (3G) mobile system. Any mode of mobile transmission is not free from channel impairment such as noise, interference and fading. These channel impairments caused signal distortion and degradation in s...
