“…In a BPSK modulation, the sinusoidal carrier signal's phase is altered in consistent with the message bit's values without changing frequency and amplitude [15,18]. In BPSK, the modulated signal is represented by the positive value of the carrier signal when the message data is 1, while it represented by the negative value of the carrier signal when the message data is 0 [19,20].…”

FPGA (Field Programmable Gate Array) based implementations of digital and analog modulation techniques play a vital rule in the design of signal processing system. The performance and flexibility provided by reconfigurable computing speeds up the development process in signal processing implementations using FPGA. Different methods for digital and analog modulation are designed in this paper by usinSg System Generator tools & Vivado. Then all designed systems are implemented successfully in an FPGA hardware via the NEXYS 4 DDR with ARTIX 7 XC7A100T. A comparison between five types of digital modulation techniques is discussed in terms of resources utilization in FPGA hardware. And also, the implementation of analog modulations in FPGA is contributed in this work. The hardware implementation shows that the number of slice LUTs in ASK modulation is 0.07% while in FSK modulation is 0.13% of the total number of slice LUTs. And also, the number of bounded IO that used for PSK modulation is 4.8% while in PM modulation is 61.4% of the total number bounded IO.

This paper presents modulation classification method capable of classifying MFSK digital signals without a priori information using modified covariance method. This method using for calculation features for FSK modulation should have a good properties of sensitive with FSK modulation index and insensitive with signal to noise ratio SNR variation. The numerical simulations and investigation of the performance by the support vectors machine one against all (SVM-OAA) as a classifier for classifying 6 digitally modulated signals which gives probability of correction classification up to 85.85 at SNR=-15dB.
