Abstract: In this paper, we describe and evaluate a novel symbol synchronization algorithm for orthogonal frequency division multiplexing (OFDM) systems especially suited for channels with very long ...

This paper proposes a 60 GHz RoF system implementation using 16-QAM, OFDM with training and pilot symbol. It is also realized with optical heterodyning, coherent detection, channel estimation and ...

(c) A picture of the components involved in the experiment. In this paper, two equalizers were studied to recover the mapped symbols transmitted. The first one is OTE normally used in common OFDM ...

OFDM(nFreqSamples=64, pilotIndices=[-21, -7, 7, 21], pilotAmplitude=1, nData=12, fracCyclic=0.25, mQAM=2) OFDM encoder and decoder. The data is encoded as QAM using the komm package. Energy dispersal ...

For DFT-spread OFDM signal, each QPSK symbol is carried on all data-carried subcarriers when single-band DFT spread is realized. In the circumstances, serious ISI on high-frequency subcarriers are ...

OFDM is very spectrally efficient ... Phase I of the P25 project uses a four-symbol FSK (4FSK) modulation. Standard FSK, covered earlier, uses two frequencies or “tones” to achieve 1-bit ...

The third axis, coming out of the page, is time, allowing us to see the OFDM signal progressing from the back of the graph to the front. Each symbol shown in the figure is one set of OFDM subcarriers ...

the OFDM symbols are demodulated and sent back to the computer. The DSP TMS320C6678 platform deployed presents a high performance multicore processor with 8 cores, each core can reach 1.25 GHz, ...
