Some (Known) Facts on Multicarrier Communication

چکیده
It is widely known and accepted that multicarrier communication is effective in frequency selective channels if resource allocation strategies are used, namely per-subcarrier adaptive modulation and coding. We discuss its efficiency for uniform resource allocation in terms of fundamental information-theoretic measures. These results are relevant to broadcast systems and, more generally, systems which cannot rely on a feedback channel.

Performance Evaluation of DWT-FDM and FFT-OFDM for Multicarrier Communications Systems using Time Domain Zero Forcing Equalization
Other than the conventional fast Fourier transform (FFT) for multicarrier modulation, a new approach for multicarrier modulation (MCM) has been known. Meanwhile, multicarrier modulation involves dividing the broadband channel into many orthogonal but overlapping narrowband carriers. In an OFDM modulation based multicarrier system using the FFT, a cyclic prefix (CP) is inserted after each symbol...
متن کاملReceiver window design for multicarrier communication systems
Multicarrier modulation formats have been chosen for some recent wireline and wireless communication systems. These systems use the Fourier transform to convert a convolutive channel into multiple memoryless subchannels, which allows for simple equalization at the receiver. However, because the received signal is windowed in time, noise is spread between subchannels. As a result, narrowband int...
متن کاملA Simple Mode Identification Algorithm for Multicarrier Signals for Software Defined Radio-based Receivers
In this paper, a mode identification algorithm for multicarrier communication modes will be presented and discussed. More precisely, the reference application is a Software Radio context where a Software Defined Radio (SDR)-based receiver is employed. This should be able to identify and classify the presence of two available multicarrier signals: Orthogonal Frequency Division Multiplexing (OFDM...

Multicarrier modulations attract a lot of attention among researchers working in the field of telecommunications. One specific form of multicarrier modulation referred to as OFDM has been the dominant technology for broadband multicarrier communications. In spite of their many advantages, OFDM systems have a few, but important drawbacks. Filter bank multicarrier (FBMC) is an evolution with many...
متن کاملSpreading sequences for multicarrier CDMA systems
The paper contains an analysis of the basic criteria for the selection of spreading sequences for the multicarrier CDMA (MC-CDMA) systems with spectrum spreading in the frequency domain. It is shown that the time-domain crosscorrelation function between the spreading sequences is not a proper interference measure for the asynchronous MC-CDMA users. Therefore, the spectral correlation function i...
