    OFDM (Orthogonal Frequency Division Multiplexing) is a well known technique in 4G Broadband wireless communication systems. OFDM has high spectral efficiency but it suffers from frequency offset problem due to the difference between transmitter and receiver local oscillator frequencies which causes loss of orthogonality between subcarriers leading to ICI. This...

    Complementary Cumulative Distribution Function for Performance Analysis of OFDM Signals

    Peak-to-Average Power Ratio (PAPR) is an important parameter for the analysis of Orthogonal Frequency Division Multiplexing (OFDM) signals. CCDF curves are known to have great importance in the study of signal performance on the basis of power level. This paper presents the CCDF performance of the OFDM signal with different...

    Qualitative and Quantitative Performance Evaluation of Adhoc on Demannd Routing Protocol in Manet

    A Mobile Ad hoc NETwork (MANET) is a network consisting of a set of wireless mobile nodes that communicate with each other without centralized control or established infrastructure. Every node in MANET moves arbitrarily making the multi-hop network topology to change randomly at unpredictable times. There are several familiar routing...
