BER of high-speed OFDM systems in the presence of offset mismatch of TI-ADCs [PDF]
, 2015 Time-interleaved analog-to-digital converters (TI-ADCs) are widely used for multi-Gigabit orthogonal frequency division multiplexing (OFDM) systems because of their attractive high sampling rate and high resolution. However, in practice, offset mismatch,

Reed Solomon Coding in Orthogonal Frequency Division Multiplexing (OFDM) Communication Systems
Journal of Engineering and Sustainable Development, 2012 This paper presents a MATLAB simulation that has been developed to investigate Orthogonal Frequency Division Multiplexing (OFDM) communication system using Reed Solomon (RS) Coding process. The efficient encoding and decoding algorithm, and the powerful of error correction capability of Reed Solomon Coding make it one of the most widely used error ...

Other-Cell Interference Reducing Resource Allocation in OFDM-Based Asynchronous Cellular Systems
EURASIP Journal on Wireless Communications and Networking, 2008 Orthogonal frequency division multiplexing (OFDM) is considered as one of the most promising techniques for next-generation wireless access systems. However, it may suffer from the so-called other-cell interference (OCI) in cellular environments. In this
