High Rate Coded Ofdm with Channel Equalization
نویسنده
چکیده
We consider the use of wideband systems for the fixed pointto-point transmission of coded data with low hit-error rate requirements. A system is defined which is based (in OFDM transmission with PSK and QAM subcarrier modulation, error control coding using low-density parity-check (LDPC) codes, and channel equalization to reduce intersymbol interference from a fading channel. Tradeoffs between modulation parameters and equalization complexity are also discussed. High rate LDPC codes are considered for this system.

متن کاملTurbo coded OFDM/TDM with Frequency-domain Equalization
Orthogonal frequency division multiplexing (OFDM) combined with time division multiplexing (TDM) bridges the conventional OFDM and single carrier (SC) transmission. For a coded OFDM/TDM system with frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion in a frequency-selective fading channel, there is a trade-off between coding gain and frequency diversity effec...

The main objectives of iNET (Integrated Network Enhanced Telemetry) are increased data rate and improved spectral efficiency [1]. In this paper we propose that transmission scheme for the physical layer is coded 16-QAM OFDM (Quadrature Amplitude Modulation-Orthogonal Frequency Division Multiplexing) which enables high data rate and spectrum efficiency. However in high mobility scenarios, where ...
