Abstract :
Orthogonal Frequency Division Multiplexing (OFDM) is a digital transmission technique used both in wired and wireless communication systems to achieve higher data rates. The idea of OFDM is to split the total transmission bandwidth into a number of orthogonal subcarriers which are transmitted in parallel. In this paper the performance of OFDM baseband receiver is analyzed for various received signal impairments. The impairments considered includes phase offset, frequency offset and synchronization mismatches. Finally the quantization of these observations are carried out.
