“…The RF module converts RF analog signals to baseband digital signals and vice versa, and it facilitates RF receiving and transmitting. The communication protocol in the physical layer is realized by the digital baseband processing module, which ensured signal encoding/decoding, and facilitated modulation and demodulation [13]. The structure of the software radio system is shown in Fig.…”

Existing software radio platforms constructed by discrete devices have many disadvantages, such as high power consumption, high cost, and poor portability. In this study, an AD9361-based software radio communication system was designed on the basis of the zero-IF bandpass sampling software radio structure to solve the poor universality and expansibility problem of traditional software radio receivers. In the AD9361-based software radio communication system, the influences of channels on received signals and the inter-symbol interference caused by the multipath configuration are offset and eliminated by the minimum mean-squared error (MMSE) equalization algorithm. The simulation analyses on the core functions, including group detection, frame synchronization, channel estimation, and frequency-domain equilibrium, of the designed receiver was performed by ModelSim. The receiving functions of the software radio were realized by the core radio frequency (RF) board of AD9361 and the digital baseband development board of ZC706. The signal frequency spectra received and sent by the designed receiver overlap on the basis of the joint debugging and testing of the RF and digital baseband modules. Test results demonstrate that the designed software radio receiver has a reasonable structural design and can meet the design requirements in terms of overall performance. Additionally, the repeated development process of traditional software radio receivers is simplified, and the integration level and expansibility of the system can be improved. The results can provide valuable references for the development of universal software radio receivers.

“…With the rapid development of wireless communication systems, software defined radio (SDR) has been more attractive to support various applications such as WIFI, WCDMA, GSM, short-wave radio and radar [1,2,3]. Direct conversion receiver (DCR) architecture is the most common solution to SDR for its flexibility and reconfigurability [4].…”

This paper presents a DC offset calibration (DCOC) method combined with analog and digital circuits for direct conversion receivers. To work effectively, the LNA is shut off for better isolation and replaced by an equivalent resistance to keep the same transfer function of DC offset between calibration and operation. This method adopts DACs to compensate DC offset, then averages and eliminates the residual DC offset in the digital domain. Measurements show that this DCOC method achieves 0.44 mV DC offset and improves IM2 by 10 dB. The DCOC circuits occupy 0.23 mm 2 in 40 nm CMOS and consume 124 µA at 1.3 V supply.

In the recent past, the software defined radio (SDR) using Multiple-Input-Multiple-Output Orthogonal Frequency Division Multiplex (OFDM) is implemented to improve the data rate and channel estimation with high spectrum and maximum throughput for short range communication. The short range of communication is established to communicate the data between different nodes placed in the appropriate position using localization technique using SDR MIMO OFDM. The 256-M Array Quadrature Amplitude Modulation (256 M-Ary Quartrature Amplitude Modulation) is applied to SDR MIMO OFDM to reduce Modulation Error Rate (MER) for efficient transmission of data through SDR. The high data rate is achieved by applying the beam-forming equalization technique by applying beam-forming between transmitter and receiver of SDR. The Zero-forcing-beam-forming (ZFBF) equalizer is used in frequency domain to correlate transmitter and receiver to improve the spectrum efficiency better. The synchronization error is reduced in the transceiver of SDR by reducing Carrier Frequency Offset (CFO) mismatch and Sampling Time Offset (STO). The simulation results have proved that the proposed algorithm have better performance in data rate improvement with elimination of CFO mismatch problem to improve the spectrum efficiency and higher range of channel estimation.
