“…The UHF band was used for downlink while the VHF band was used for uplink, and the SDR platform was immediately used in the CubeSat without intervention from HAVELSAT team [43]. Another example of this development approach is the USRP-based SDR system described in [44]. Such CubeSat designs are not part of this review since they are not concerned with the communication research-oriented design element that this paper aims to review.…”

This survey 1 fills in an important gap in the literature on CubeSat communication systems’ designs and architectures. The paper 2 comprehensively reviews the design details in-depth and 3 critically evaluates the performance and reliability of the reviewed systems by analyzing the demonstration and testing results and illustrating implicit assumptions in the reviewed works. Furthermore, the paper 4 proposes an original CubeSat communication system categorization based on the design approach and 5 analyzes the features and limitations of each category. Consequently, this leads to identifying the limitations of current CubeSat communication systems and the promising future developments that can boost CubeSat communications capabilities.

“…Among the published list, there are three libraries that stand out for its frequent use in a great amount of the current research papers. The first of them appear in 2001 and it was designed exclusively for Linux operative system, but its popularity [45][46][47] has extended its usage also to Windows: GNU Radio2001.The other two operate exclusively on Windows and are based on MATLAB mathematical software: Karlsruhe Institute of Technology-MATLAB/Simulink/USRP2009 and MathWorks-MATLAB/Simulink/USRP2011. Precisely together with GNURadio, MATLAB is the most used support in SDR investigations [48][49][50].…”

The author makes a review of the SDR (Software Defined Radio) technology, including hardware schemes and application fields. A low performance device is presented and several tests are executed with it using free software. With the acquired experience, SDR employment opportunities are identified for low-cost solutions that can solve significant problems. In addition, a list of the most important frameworks related to the technology developed in the last years is offered, recommending the use of three of them.

This paper reports on the design and performance of a new Variable Coded Modulation (VCM) system. This VCM system comprises eight of NASA's recommended codes from the Consultative Committee for Space Data Systems (CCSDS) standards, including four turbo and four AR4JA/C2 lowdensity parity-check codes, together with six modulations types (BPSK, QPSK, 8-PSK, 16-APSK, 32-APSK, 64-APSK). The signaling protocol for the transmission mode is based on a CCSDS recommendation. The coded modulation may be dynamically chosen, block to block, to optimize throughput.A novel aspect of the VCM design is that each operating mode has a unique number of symbols in its frame. This enables the receiver to identify the code and modulation simply from the number of symbols occurring between the dedicated frame markers which occur between frames, without having to explicitly transmit a signal to identify the operating mode. This concept allows for a limitless selection of modes and low complexity design.The paper describes a MATLAB end-to-end simulation consisting of random data generation, encoding the data, modulation of the data, additive white Gaussian noise for channel simulation, frame marker identification, coded modulation mode extraction, demodulation, and decoding. Achievable error rates and total throughput are recorded. This simulation can be applied to any link budget that describes the signal to noise ratio over time and can selectively use all or some of the supported coded modulation modes.The simulations show that for a representative low-Earth orbit satellite which encounters a 15 dB variation of symbol SNRs in a 10 minute pass, VCM doubles the achievable throughput, compared to the optimal fixed-mode communication. This simulation shows that VCM is a major and practical method for communicating high data volumes from space.
