Constant-Envelope OFDM and Constant Envelope SC-FDMA
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
