发明名称 OFDM-TRANSMITTING APPARATUS AND METHOD AND OFDM-RECEIVING APPARATUS AND METHOD
摘要 A method of transmitting data via an Orthogonal Frequency Division Multiplexed (OFDM) symbol, includes forming data symbols into pairs, generating a first pair of modulation symbols for each of the pairs of data symbols, the first pair of modulation symbols forming first and second modulation symbols of an Alamouti cell, forming a first version of the OFDM symbol by modulating the sub-carriers allocated for carrying the data with the first and second modulation symbols of the Alamouti cells, and modulating the one or more pilot carriers of the first version of the OFDM symbol. The method also involves generating a second pair of modulation symbols for each of the pairs of data symbols, the second pair of modulation symbols forming third and fourth modulation symbols of the Alamouti cell formed for the pair of data symbols in the first version of the OFDM symbol, forming a second version of the OFDM symbol by modulating the sub-carriers allocated for carrying the data with the third and fourth modulation symbols of the Alamouti cell, modulating the one or more pilot carriers of the second version of the OFDM symbol or symbols, and transmitting the first version of the OFDM symbol via a first antenna, and the second version of the OFDM symbol via a second antenna. For at least one of the pairs of data symbols, the sub-carriers, on which each of the first and second modulation symbols and the third and fourth modulation symbols forming the Alamouti cells, are separated within the first and second versions of the OFDM symbol by at least one other data bearing subcarrier or one or more of the pilot carriers. A transmitter and/or receiver according to the invention find application with the Digital Video Broadcast- Terrestrial 2 (DVB-T2) standard.
