Orthogonal frequency division multiplexing (OFDM) has become attractive for many current and emerging commercial applications because it provides a combination of data throughput, scalability, and ...

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 ...

As designers begin turning to orthogonal frequency division multiplexing (OFDM) in system architectures, they will quickly realize that implementing this modulation scheme is not an easy task.

This series is excerpted from “Mobile Broadband Multimedia Networks: Techniques, Models and Tools for 4G.” Part two shows how to enhance OFDM with MIMO and other techniques. The many papers noted in ...

Telecom network equipment vendor ZTE today said it has demonstrated real-time transport and coherent detection of 100G orthogonal frequency division multiplexing (OFDM) signal. The Chinese telecom ...

Over the past year I’ve been writing about potential transmission standards for a nextgeneration broadcast platform (NGBP). The most promising standards are all based on orthogonal frequency division ...

In this paper we present a set of embedded digital signal processors to build a programmable OFDM receiver that can address a variety of broadcast formats as used for both digital television and ...

OFDM is a multi-carrier system where data bits are encoded to multiple sub-carriers, while being sent simultaneously. This results in the optimal usage of bandwidth. A set of orthogonal sub-carriers ...

Digital terrestrial broadcasting employs a multi-carrier transmission technology called orthogonal frequency division multiplexing (OFDM). To enhance broadcasting services for mobile reception, we are ...

In last month’s column I described the principles behind OFDM, how it is generated and received and different parameters that can be adjusted to optimize the transmission for different uses. This ...
