Abstract-To meet the requirements of wireless communication industry Software-Defined Radio (SDR) provides an efficient, re-configurable and high performance platform to integrate all individual functions for various modulation and demodulation techniques. The key design step is to determine the digital hardware components of a software radio. This system consists of the BPSK Modulated Radio transmitter and receiver using Linux based GNU radio system. This work presents how the GNU Radio Companion (GRC) and USRP have been used to transmit/receive signals for a wide range of frequencies. The main advantage of this project is that we can implement any transmitter or receiver system without changing the hardware. We have to just change the parameters of software blocks [2] and the low bit error rate.

Advancements in wireless communication systems have positioned digital communication as a fundamental technology. Among the array of digital modulation methods, Amplitude Shift Keying (ASK) holds a significant position. This study centrally involves the simulation of the ASK modulation scheme using MATLAB software, accentuating practicality in design and execution. Notably, the correlation between simulated results and practical implications stands as a noteworthy achievement. The investigation demonstrates the conversion of a Unipolar return-to-zero square pulse message signal into a sinusoidal form, facilitating seamless transmission to the endpoint. Three key elements structure this study: the generation of the message signal, the creation of the carrier signal, and their amalgamation to generate the ASK signal. Diverse integrated circuits are employed, encompassing the utilization of a 555 timer to generate the message signal, an LM324 quad operational amplifier chip for carrier signal generation, and a CD4016 multiplexer chip for ASK signal generation. The simulated ASK system closely aligned with the practically designed setup, validating the accuracy of the theoretical model. This convergence can be attributed to meticulous considerations in circuit design and the careful selection of standard values, resulting in a compelling correlation between simulation predictions and real-world implementation. The graphical representation of the ASK signal, plotted via MATLAB, exhibited a remarkable match between theoretical and practical outputs. Furthermore, the outcomes suggest promising avenues for future exploration. One such direction involves enhancing the system's capacity by implementing an M-ray ASK system, a potential means to augment data transmission rates beyond the binary framework. Additionally, introducing randomness to the binary signal through the integration of a binary number generator emerges as a prospective area for future enhancements

“…Limited available frequency spectrum, channel impairment, and difficulties in designing hardware for high speed or problem in dealing high frequency electronics are the reason for limited data rate in wireless networks . To increase the date rate in wireless transmission, digital modulation and multiple access techniques are attractive solutions . In wireless parallel data transmissions, order of modulation has an important role in the enhancement of the data rate but it also increases the complexity of the system.…”

A frequency diplexer network for ultrawideband radios focused on wireless parallel data transmission is presented. It has a combination of two bandpass filters utilizing manifold multiplexing technique. In the frequency band 6–9 GHz, two flat sub‐bands at center frequencies 6.7 and 8.3 GHz have been achieved with respect to forward transmission, input reflection, and group delay. A maximum group delay variation of 0.6 ns was measured in the sub‐bands. For low cost and simple circuit implementation, the design is implemented using the microstrip technology. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1869–1871, 2014
