Abstract | Orthogonal frequency division multiplexing (OFDM) is sensitive to the phase nonlinearity due to filter devices in both transmitter and receiver. In this paper, the bit error rate (BER) performance degradation of OFDM systems with phase nonlinearity is investigated in an additive white Gaussian noise (AWGN) channel. We consider the effects of BER both in parabolic and cubic phase nonlinearity. The theoretical approximate calculation method is also derived of BER for binary phase shift keying (BPSK) and quaternary phase shift keying (QPSK) modulation schemes in OFDM systems. In addition, the method of BER calculation is validated by simulations. In general, phase shift keying modulation schemes is easily affected by phase nonlinearity in transmitting channel. Especially in high data rate transmitting system, phase nonlinearity will make great degradation in BER. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
