It is very important to achieve high performance in the SC-FDMA (Single Carrier Frequency Division Multiple Access) system that is used for LTE (Long Term Evolution) and LTE-advanced system. To simultaneously resolve ICI (Inter-subCarrier Interference) and PAPR(Peak to Average Power Ratio) problem, focused on the two Transmit(Tx) /one Receive(Rx) antenna configuration, phase noise influence on the 21 SFBC (Space Frequency Block Coding) SC-FDMA system is first analyzed, then compared with MISO (Multiple Input Single Output) SC-FDMA using several selected ICI self-cancellation methods. SC-FDMA induces more interference problem than OFDM because of the DFT spreading phase offset mismatch caused by random phase noise.
