RF signal is ease to be interfered, which makes the signal of transmitting and receiving impure to impact on wireless communication. It is not to be ignored for interfering between transceiver signals in package of transceiver, thus, insulating enough must be taken. In addition, the mount of noise introduced through a main interference source being from contribution of digital signal continuously...
This article investigates novel adaptive self-interference cancellation solutions and the total integrated cancellation performance of a mobile single-antenna inband full-duplex transceiver. First, novel self-adaptive digital self-interference cancellation algorithms are described, with an emphasis on tracking of time-varying self-interference coupling channel in a mobile device as well as on structural...
An insulated signal transmission system using planar resonant coupling technology has been developed for providing driving signal transmission to control power electronic equipment. The resonant coupling can reduce the unwanted leakage that prevents conventional wireless systems from being applied inside the equipment. Using planar resonant couplers, the system restricted propagation loss to −0.9...
This paper presents RF front end architecture and design techniques to enable co-existence among multiple standards in multi-comm SOC products. The design practices presented in this paper are derived from two generation of products designed in 90nm CMOS process for 802.11abgn Wifi and Bluetooth (BT) application. A novel shared LNA architecture is proposed for Wifi and BT front end along with mixer...
A complete single package communicator (SPC) designed and implemented for 3G modem in 400 mm2 size and 1.3 mm height, for the first time is presented. With the help of 3-D technology, development of highly integrated active/passive components and use of latest packaging technology, the design was doable. Optimization of the RF performance of all GSM and WCDAM channels was obtainable despite the small...
In this work, some most frequently studied interconnect solutions in recent years have been discussed and compared to show their advantages and limitations. RF wireless interconnect (RFWI) method is further studied by system modeling in simulink environment and successful communication between transmitter and receiver is obtained. The results indicate the potential feasibility and reliability of the...
