Radio receiver, as an extensively feasible modern technology, has been widely applied in all fields of military and civil. It is mainly to demodulate all kinds of required signals with strong interference and noise. Based on intermediate frequency (IF) software radio receiver test platform, the data transmission approach combining direct memory access (DMA) and multichannel buffered serial port (McBSP) was studied and the parallel operation of data transmission and data processing was realized. The method proposed for signal transmission and processing shows strong universality and can be used in other relevant fields.

This paper presents a novel scheme for software radio receiver application, which integrates a high-speed digital down converter (DDC) block into a SoC (system on chip) based on OR1200 CPU. The proposed design can transform intermediate frequency (IF) signal to baseband signal and realize the real-time baseband signal processing. The simulation results indicate that the design is capable of accepting data at a 200MHz sample rate and the verification results based on Xilinx FPGA show that the SFDR of DDC can reach to 70.59dBFS.The synthesized results on 0.18um CMOS technology reveal that the maximum clock frequency can reach to 116MHz and the total area is 5.662mm2, and the corresponding power consumption is below 150mW. It should have a good potential for wireless communication applications.

Bicmos Technology

A fully integrated transmitter (TX) and receiver (RX) front-end chipset, produced in 0.25 µm SiGe:C bipolar and complementary metal oxide semiconductor (BiCMOS) technology, is presented. The front-end is intended for high-speed wireless communication in the unlicensed ISM band of 9 GHz around 60 GHz. The TXand RX features a modified heterodyne topology with a sliding intermediate frequency. The TX features a 12 GHz in-phase and quadrature (I/Q) mixer, an intermediate frequency (IF) amplifier, a phase-locked loop, a 60 GHz mixer, an image-rejection filter, and a power amplifier. The RX features a low-noise amplifier (LNA), a 60 GHz mixer, a phase-locked loop (PLL), and an IF demodulator. The measured 1-dB compression point at the TX output is 12.6 dBm and the saturated power is 16.2 dBm. The LNA has measured noise figure of 6.5 dB at 60 GHz. Error-free data transmission with a 16 quadrature amplitude modulation (QAM) orthogonal frequency-division multiplexing (OFDM) signal and data rate of 3.6 Gbit/s (without coding 4.8 Gbit/s) over 15 m was demonstrated. This is the best reported result regarding both the data rate and transmission distance in SiGe and CMOS without beamforming.

Currently, centrally reserved access to the medium in the digital radio communication networks of the IEEE 802.11 family standards is an alternative to random multiple access to the environment such as CSMA/CA and is mainly used in the transmission voice and video messages in real time. Centrally reserved access to the environment determines the scope of interest in it from attackers. However, the assessment of effectiveness of centrally reserved access to the environment under the conditions of potentially possible destructive impacts was not carried out and therefore it is impossible to assess the contribution of such impacts to the decrease in the effectiveness of such access. Also, the stage establishing of centrally reserved access to the environment was not previously taken into account. Analytical model development of centrally reserved access to the environment under the conditions of destructive influences in digital radio communication networks of the IEEE 802.11 family standards. A mathematical model of centrally reserved access to the environment has been developed, taking into account not only the stage of its functioning, but also the stage of formation under the conditions of destructive influences by the attacker. Moreover, in the model the stage of establishing centrally reserved access to the medium displays a sequential relationship of such access, synchronization elements in digital radio communication networks and random multiple access to the medium of the CSMA/CA type. It was established that collisions in the data transmission channel caused by destructive influences can eliminate centrally reserved access to the medium even at the stage of its establishment. The model is applicable in the design of digital radio communication networks of the IEEE 802.11 family of standards, the optimization of such networks of the operation, and the detection of potential destructive effects by an attacker.
