Abstract :
A new out-of-band power suppression method for single carrier (SC)-orthogonal frequency division multiplexing (OFDM) is proposed in this letter. In the proposed method, by inserting two static "anchor symbols" at designated positions in every SC-OFDM block, phase continuity between SC-OFDM blocks is preserved and out-of-band power emissions are reduced without bit error rate (BER) performance degradation. Both experimental and simulation results indicate that reduction of out-of-band emissions up to 13dB can be achieved by using the proposed method.
