“…Similarly, a finite-power signal x(t) is said to be second-order almost conjugate cyclostationary in the wide-sense if its CCF (2) can be expanded (with respect to t) in a generalized Fourier series as in (3), where R β xx * (τ ) in lieu of R α xx (τ ) denotes the cyclic CCF at conjugate cycle frequency β ∈ B ⊂ R, whose expression can be obtained by ( 4) by replacing α with β and x * (t − τ ) with x(t − τ ), respectively. Also in this case, if all conjugate cycle frequencies β can be expressed as a multiple of some 1/T 0 , that is B ≡ {m/T 0 } for m ∈ Z, the process x(t) is said to be second-order widesense conjugate cyclostationary with period T 0 .…”

“…According to Mitola [1], the term software-defined radio (SDR) identifies a class of radios that can be reprogrammed and reconfigured through software. The adoption of SDR low-cost development platforms is envisioned as a key enabler for many aerospace applications, such as unmanned aerial vehicles (UAVs) [2], small satellites [3], or deep space communications [4]. Indeed, in operating scenarios char-979-8-3503-0462-6/24/$31.00 ©2024 IEEE.…”

In this paper, we present a first attempt to incorporate in the GNU Radio ecosystem a tool called CycloDSP, devoted to the analysis of complex-valued cyclostationary signals. Such signals are ubiquitous in communication and signal processing, exhibiting periodic or almost periodic statistics that are characterized by a countable set of cycle frequencies, which are related to the main signal periodicities. Common cycle frequencies for modulated signals are multiple of the baudrate and/or combination of the carrier frequency and baudrate. Conventional estimation strategies for cyclostationary signal analysis typically exhibit a high computational burden. Many approaches aimed at reducing complexity exploit fast Fourier transform (FFT) algorithms, which are very efficient for batch data but are not suited for continuously streaming data, typically encountered in software-defined radio (SDR) applications. The aim of this paper is to develop an out-of-tree (OOT) GNU Radio module containing a set of building block functions, aimed at estimating functions, such as the cyclic correlation functions, typically employed for cyclostationary signal analysis. The proposed implementation must be designed so as to ensure high efficiency in processing continuous data streams of complex samples, both in terms of computational load and data storage, in order to be executed on general purpose computers. We tested our implementation by estimating in real-time the second-order cyclic statistics of a Gaussian minimum-shift keying (GMSK) modulated signal, which belongs to a class of signals commonly employed in aeronautical telemetry datalinks.

Software defined radio (SDR) has become a popular tool for the implementation and testing for communications performance. The advantage of the SDR approach includes: a re-configurable design, adaptive response to changing conditions, efficient development, and highly versatile implementation. In order to understand the benefits of SDR, the space telecommunication radio system (STRS) was proposed by NASA Glenn research center (GRC) along with the standard application program interface (API) structure. Each component of the system uses a well-defined API to communicate with other components. The benefit of standard API is to relax the platform limitation of each component for addition options. For example, the waveform generating process can support a field programmable gate array (FPGA), personal computer (PC), or an embedded system. As long as the API defines the requirements, the generated waveform selection will work with the complete system. In this paper, we demonstrate the design and development of adaptive SDR following the STRS and standard API protocol. We introduce step by step the SDR testbed system including the controlling graphic user interface (GUI), database, GNU radio hardware control, and universal software radio peripheral (USRP) tranceiving front end. In addition, a performance evaluation in shown on the effectiveness of the SDR approach for space telecommunication.

Mehrpouyan has been a source of great inspiration for me. I joined BSU three weeks after the start date of the fall 2015 semester, but with the kind support of my supervisor, I was able to adjust well to the new environment. I am deeply impressed by the work ethic and professionalism of Dr. Hani. He will always be my mentor. Dr. Hani Mehrpouyan helped me understand advancements in millimeter-wave (mm-Wave) technology. Without the support of Dr. Hani, I would not have been able to accomplish my research goals. In Dr. Hani, I have found a person with the highest level of professionalism and a kind heart. Along with his research, Dr. Hani has also inspired me with his towering personality and gratitude. I am fortunate to be his student. I am also incredibly thankful to Dr. Nader Nafla and the ECE department at Boise State University for providing me with an extremely favorable environment for research and assisting me in my first patent. I am also thankful to Muhammad Kamran Latif, Ruhollah Amiri and Luka Dawood for helping and assisting me during my research. Muhammad Kamran Latif was always there to help. He also provided me with great emotional and logistic support during my time at Boise.
