Effect of variable guard time length on mobile WiMAX system performance
Guard time length (GT) is one of the key OFDMA parameters. It is implemented as cyclic prefix (CP) to completely alleviate intersymbol interference (ISI) and to preserve orthogonality among OFDMA subcarriers as long as the guard time length is sufficiently greater than channel delay spread. In conve...
