Abstract	Carrier aggregation (CA) is a technique introduced in LTE-Advanced to achieve a higher throughput by increasing bandwidth. In this work, the spectrally efficient frequency division multiplexing (SEFDM) bandwidth compression technique is utilized to enhance CA performance. This work reports experimental demonstration of SEFDM and shows that up to 7 component carriers (CCs) can be aggregated in a given bandwidth with guaranteed bit error rate (BER), while orthogonal frequency division multiplexing (OFDM) can only pack 5 CCs in the same bandwidth. Full system description and experimental set up are given in the paper together with BER results for SEFDM and OFDM based systems using LTE-like frame and signal formats and transmitted over an LTE standard fading channel. Experimental results show the bandwidth advantages of SEFDM and confirm that the effective spectral efficiency of aggregated SEFDM is much higher than that of aggregated OFDM.
