In recent years, there is a dramatic increase in the number of cellular devices. As a result, the

wireless network traffic increased as well. 4G, the most recent developed technology, soon

will not be good enough to fulfill the increasing need for capacity in the mobile data network.

As a consolidation of previous generation technologies, 5G is brought up as a solution. The

standardization for 5G is not established yet. Therefore, modulation techniques that can be

employed in 5G and which can support the need for the increased capacity are investigated.

In this thesis, modulation techniques CE-OFDM and CE-SC-FDMA are being investigated.

Their bit error rate performance is compared. It is found that both systems have close bit

error rate performance. A power amplifier is added to both systems and it is found that

power amplifier has no impact on the performance. Furthermore, CE-OFDMA and CE-

SC-FDMA are investigated and their bit error rate performance is found to be similar as

well.
