- LTE Coordinated Multipoint (CoMP) enables the coordination of transmission and reception over a variety of different base stations. In CoMP-OFDM systems, the multiple transmitters must be synchronized to prevent mutual interference. Applying CoMP transmission, a receiver must estimate multiple CFOs corresponding to the multiple receiving signals for compensation. However, the different signals interfere with each other at the receiver, and this mutual interference significantly degrades CFO estimation performance. Therefore it is difficult to obtain a good estimate of the CFOs. In this paper, fractional CFO in the range of -1 to +1 subcarrier spacing is estimated for multiple base station(BS). The mutual interference and variations to CFO is also minimized.
