Abstract:
A universal transmitter and a universal receiver for respectively transmitting and receiving orthogonal frequency-division multiplexing (OFDM) signals using the international television bands respectively use fixed subcarrier spacing; fixed Fast Fourier Transform (FFT)/Inverse Fast Fourier Transform (IFFT) period values; a fixed symbol duration for each cyclic prefix option; and fixed WRAN frame parameters, but a selectable channel bandwidth for transmission and reception.
