This paper deals with capacity enhancement of the Filter bank based multicarrier with Offset-QAM systems (FBMC/OQAM) using precoding technique. FBMC/OQAM is one of the candidate waveform for future fifth generation (5G) mobile communication systems. Its advantages are twofold: Using orthogonal carriers and higher data rate compared to OFDM system. By introducing filter bank techniques, no cyclic prefix (CP) is required in FBMC/OQAM therefore capacity increase. In this paper we insert a precoder to cope with channel effect at each subcarrier. Optimizing system capacity using precoder is equivalent to constrained convex optimization problem.
