Abstract |
Communication is the most important factor for the development of the human society. There are many technologies for the establishment of the effective communication such as satellite communication, wireless communication, wired communication, power line communication etc. there are various modulation techniques are available for secured and noise free communication. Orthogonal Frequency Division Multiplexing (OFDM) is the one of the efficient method which is used to establish such communication. Added Impulsive Noise is one of the factor who degrades the OFDM efficiency. Many methods are proposed to reduce the impact of added impulsive noise in low order OFDM communication and higher order OFDM communication as well. QPAK, 16QAM, 32 QAM modulation schemes are the examples are lower order modulation and 64QAM, 128 QAM and 256 QAM are higher order modulation schemes. This paper shows the study on added impulsive noise removal schemes for lower and higher order OFDM communication. |
