Single carrier frequency division multiple access (SC-FDMA) for filter bank multicarrier communication systems [PDF]
Proceedings of the 5th International ICST Conference on Cognitive Radio Oriented Wireless Networks and Communications, 2010 The Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) radio standard has adopted a special form of orthogonal frequency division multiplexing (OFDM) method for the uplink of multiple access networks. This method which is called single carrier frequency division multiple access (SC-FDMA) applies a precoding to each user data set in ...
