Abstract :
In this paper, CPFSK-OFDM systems which use CPFSK (Continuous Phase Frequency Shift Keying) as the first modulation scheme of OFDM (Orthogonal Frequency Division Multiplexing) are considered. We implemented CPFSK-OFDM systems by using software defined radio and evaluated them in an AWGN (Additive White Gaussian Noise) channel. We found that the performance is better when the modulation index of CPFSK is 0.75. In the future, we will evaluate our system in a fading environment.
