Investigating noise performance in direct conversion receiver system using Matlab simulink / Nor Hasnifarina Jamadin

Noise is very crucial problem in communication system for data transmission and reception of original signal. Predicting noise performance of RF system is much more complex than for linear ones. Noise which is generated either within the component of the devices can also cause distortion and interfe...
