With the popularity of smart devices in a variety of actions to drive more usage of wireless broadband networks. OTT refers to delivery of video, audio and other media over the Internet. The video-related applications and services are major challenges that impact the network performance in the future. It is important to achieve network and service traffic offloading to overcome high-speed, real-time,...
In this paper, a phase noise cancellation (PNC) architecture is presented for 60 GHz communication systems. The BER performance is severely degraded by the non-ideal carrier frequency in 60 GHz bandwidth, which causes both common phase error (CPE) and residual carrier frequency offset (RCFO). The proposed simplified two-stage CPE algorithm solves the RCFO and common phase nose in the frequency domain...
In this paper, a dual-standard, dual-mode baseband receiver for 60 GHz wireless communication is presented. The receiver is designed to support SC and OFDM modes for both IEEE 802.15.3c and IEEE 802.11ad standards. The receiver is integrated with all-digital synchronization, radix-16 FFT, phase noise cancellation and low-complexity time-domain equalizer for line-of-sight channel application. The hardware...
In this paper, a hardware implementation of Support Vector Machine (SVM) classifier for acceleration has been proposed based on pipelined adder, in which the speedups outperform other existing architectures. The adder whose critical path has been efficiently shortened by pipeline technology, constituted the main arithmetic elements in SVM processing. Therefore, a higher processing frequency and throughput...
In this paper, an 8X-parallelism digital baseband receiver is proposed for IEEE 802.15.3c application. The baseband receiver consists of all-digital synchronization, radix-16 FFT and LS-LMS equalizer modules. It supports SC and HSI dual-mode in IEEE 802.15.3c with single hardware for area efficiency. The chip is implemented with 65 nm 1P9M process. The fabricated area is 12.96 mm2 with 3463 K gate...
This paper presents an architectural technique to efficiently implement multi-stage additions through operand segmentation. Carry bypass is leveraged to break the dependency between the two segmented adders, reducing the delay of the critical path. This allows for power- and area-efficient hardware implementation due to the increased timing margin for architectural transformations at the cost of one...
Integrated Modular Avionics (IMA) software testing is critical for the quality of the IMA system. The software testing environment (STE) employed within the federated avionics is not suitable for the IMA software due to the increased complexity and dynamic reconfiguration in the highly integrated software architecture. It creates new challenges for the software testing and verification of the IMA...
In this paper, we use adaptive filter to realize the echo cancellation strategy in On-Channel Repeater (OCR) based on the National Standard of China for Digital Terrestrial Multimedia Broadcasting (DTMB). In order to reduce the computational complexity and solve the drawbacks of convergence and steady state characteristics of the conventional fix step size Least Mean Square (LMS) algorithm, this article...
