Power management and high speed transceiver I/O demands are two major challenges for advanced field programmable gate array (FPGA) at 28nm node. To meet requirements, not only innovations in process technology but also co-optimization of process, circuit and system architecture are required. Advanced process technologies, such as high-k metal gate (HKMG) and enhanced strain engineering, significantly...
We present a hardware vehicular channel emulator aimed at assessing the performance of IEEE 802.11p transceivers in realistic scenarios. Contrarily to commercial emulators, which are usually very expensive and not quite flexible, we have developed an FPGA-based solution that is cheap, flexible and reconfigurable. In this paper we outline its design, implementation and basic operation. To show its...
Advancement of field programmable gate array (FPGA) faces many challenges. Among the major ones are power management and high speed transceiver I/O demands. To overcome the challenges, process-design co-optimization is required. With co-optimization of process, circuit, and architecture, 45% static power reduction is achieved for a 40 nm FPGA design. With optimized analog devices, high data rate (8...
The universal serial bus(USB) transceiver macro cell interface (UTMI) is a two wire, bi-directional serial bus interface. The USB2.0 specifications define three types of UTMI implementations depends on data transmission rates, those are low speed (1.5 MHz) only (LS), full speed (12 MHz) only (FS) and high speed (480 MHz)/full speed (12 MHz) (HS). UTMI consists of transmitting and receiving sections,...
This paper discusses the performance of the wavelet based filtered multi-tone (WFMT) modulation. The novel WFMT modulation was proposed in 2003 for improving characteristics of wireless and DSL multicarrier systems. In this paper we describe a main idea of WFMT and discuss the advantages of this novel modulation. The WFMT modulation in comparison with OFDM and DMT has low level of out-of-band side...
In this paper, the design and implementation of a new high performance hardware channel emulator is presented. The purpose of the developed emulator is to efficiently reproduce in a laboratory environment the accurate behaviour of several effects of the radio channel over a multiple antennas wireless communication system, including AWGN (additive white Gaussian noise), multipath, attenuation and Doppler...
