FPGAs are dynamically reconfigurable, and these high-performance, programmable Systems on a Chip (SOC) have limited flexibility. DSP processors are based on the Harvard architecture, an extension of the Von-Neumann architecture, and are unable to meet SDR speed requirements despite a set of arithmetic and control instructions optimized for signal processing algorithms. ĪSICs offer the best possible performance at the lowest cost of silicon, but they suffer from a lack of flexibility and a high one-time engineering cost.

The cost functions of the computing platform are programmability, flexibility, power consumption and computing power. When designing an SDR terminal, it is necessary to choose a computing platform for the digital part, a radio front end, and to make a compromise between the sampling frequency, the complexity of the terminal and the energy consumption. The architecture of SDR systems defines the hardware abstraction layer. The concept of software-defined radio was introduced by J.

Almost all of the functionality associated with the physical layer (PHY) is implemented in software using digital signal processing (DSP) algorithms. SDR is a radio communication system, which gives the possibility of software control of modulation method, coding scheme, filtering, wideband or narrowband operations, spread spectrum techniques, bandwidth, channel access techniques and waveform requirements. All this explains the growing interest in low cost multimode terminals based on software radio techniques.

Soon they might even include radios to also receive UHF IoT and TV White Space signals. Many smartphones and similar devices currently have up to about 8 different radios optimized to receive various signals of different frequency bands and standards. In conventional transceivers, digital baseband processing is typically performed by dedicated hardware circuits, mostly rigid but power efficient ASICs. Software reconfigurability involves digitizing signals as close as possible to the antenna, because high speeds require large bandwidth. Real time without the need to physically modify the hardware. This process must be dynamic and requires the receiver to be flexible that is, adaptable and reconfigurable, more or less in Terminals must then adapt their hardware to suit wireless networks such as GSM, EDGE, UMTS, IEEE 802.11a / b / g, LTE and the booming 5G. This constant and rapid evolution of wireless and communication technologies implies online reconfigurability of receivers using software programming justifying the term software radio with a requirement for increasingly higher data rates and frequency bands.

Digital mobile communications systems tend to integrate more and more applications (GSM, radio, TV, GPS, etc.) while operating on multiple standards. Software-defined radio (SDR) makes it possible to design flexible transceivers architectures, both in frequency and in modulation format, capable of generating waveforms of all standards while respecting the output power level for each and ensuring a good performance. KeywordsSoftware-defined radio, multistandard terminal, EVM, ACLR, MER, multipath, fading channel, WLAN, LTE, 5G NR. The performance analysis and evaluation use various diagrams and signal quality measures such as Error Vector Magnitude (EVM), Modulation Error Rate (MER), Adjacent Channel Leakage Ratio (ACLR) as well as timing and frequency offsets. For each of the three standards, the transmitter and receiver systems are defined in compliance at the physical layer level with the specifications of the latest 3GPP standards. Another PlutoSDR or RTL-SDR according to the standard (signal bandwidth) is then used to capture the signal, which is synchronized, decoded and analyzed. We generate a baseband waveform that is either a WLAN Modulation and Coding Scheme (MCS), an LTE Reference Measurement Channel (RMC) or a 5G Fixed Reference Channel (FRC) synthesized in MATLAB using the appropriate toolkits, and upload it to a PlutoSDR module for live transmission. The architecture validation is performed on a multipath fading channel model and on real waveforms of three selected radio standards.
