Patent ID: 8351323

Claim:
A method for transmitting/receiving a continuous pilot code in a multi-carrier system, the method for transmitting comprising: performing a time-frequency domain two dimensional encoding on an information bit stream to be transmitted based on different system frame structures, to obtain an encoded bit stream; mapping the encoded bit stream to obtain a set of continuous pilots carrying encoded information; multiplexing a load, a discrete pilot and the continuous pilot based on distribution of the load, the discrete pilot and the mapped continuous pilot on a sub-carrier, to generate a frequency domain signal; and performing a frequency-domain-to-time-domain transform on the frequency domain symbol, to obtain time domain samples; wherein the time-frequency domain two dimensional encoding includes selecting a part of pilots from continuous pilots and encoding them; the method for receiving comprising: extracting the continuous pilots from the valid sub-carriers of a multi-carrier signal; and performing a time-frequency domain decoding on the extracted continuous pilots to obtain decoded information.
