Abstract
Official abstract text for this publication.
A method for transmitting signals in a multi-carrier radio transmission system is provided. The method includes a transmission block composed of N consecutive Orthogonal Frequency-Division Multiplexing (OFDM) symbols in a time domain and M consecutive physical sub-carriers in a frequency domain, where N and M are each an integer not less than 1. The method further includes encoding and interleaving data at a transmitting end, transmitting a pilot signal in a frequency area of a pilot stream for transmission of the pilot signal, performing, at the transmitting end, an IFFT operation on the encoded and interleaved data and the pilot signal, and transmitting, at the transmitting end, the data and the pilot signal through at least one antenna after inserting a preamble signal, wherein at least one pilot stream exists at the transmitting end, and wherein at most one pilot signal is transmitted in a group of OFDM symbols.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for transmitting signals of a transmitting end in a multi-carrier radio transmission system, the method comprising: encoding and interleaving data; inserting a pilot signal into the encoded and interleaved data; performing an inverse fast fourier transform (IFFT) transformation on the pilot signal-inserted data; and transmitting the IFFT transformed data through at least one antenna, wherein pilot signals are transmitted via pilot stre…
