As selection of the length of guard interval depends on the channel condition, the length of guard interval will change dynamically. Thus there must be a way to synchronize this parameter between the transmitter and the receivers. Traditional OFDM systems require a transmitter to notify its ...

OFDM transmission/reception apparatus with selection of the optimal guard interval lengthThe subtractor of the reception system calculates the channel quality using an optimal guard interval length detection signal inserted into one carrier by the transmission system, then the optimal guard interval length...

SC-FDE (Single Carrier with Frequency-Domain Equalization), one of physical layers of IEEE802.16, is less sensitive to nonlinear power amplifiers than OFDM while its complexity and performance is comparable. The guard interval length in ... R Minjoong - 《전자공학회논문지 tc편...
When a communication device determines that a packet (PPDU) is to use a first length of a training field and a first duration of a guard interval (GI), the communication device gene
The guard interval is greater than or equal to the memory length of the transmission channel and is transmitted without any signals or prefix and demodulation is carried out in the receiver by means of fast Fourier transformation (FFT) with a length (L) which is greater than or equal to ...
A new algorithm estimating channel impulse response (CIR) length and noise variance for orthogonal frequency-division multiplexing (OFDM) systems with adaptive guard interval (GI) length is proposed. To estimate the CIR length and the noise variance, the different statistical characteristics of the add...
