Power line communication (PLC) is one of the preferred broadband high-speed data communication technology for its wide availability, low infrastructure cost, and robustness. However, PLC performance is limited by attenuation and background noise present in the medium. The frequency shift keying (FSK) modulation scheme is experimentally found to be more robust against such power line distortions. Further,...
An 8 Gb/s/link power optimized controller memory interface is implemented in TSMC 40 nm G CMOS process. It is composed of 32 differential data links to support 32 GB/s payload. The bimodal drivers of the request bus enable support of both 12 bits of 2 Gb/s/link single-ended RSL (rambus signaling level) for existing XDRTM memory and 6 bits of 8 Gb/s/link differential signaling for next generation XDR2...
Patterned Media Storage (PMS) is one of the promising technologies to overcome the limitations of the conventional magnetic recording. While advanced signal processing and coding algorithms helps to improve the bit error rate performance of Patterned Media Storage (PMS) channel, they have to be designed by considering the underlying channel model. In literature, there are two popular channel models...
This paper presents a low power 60 GHz transceiver that includes RF, LO, PLL and BB signal paths integrated into a single chip. The transceiver has been fabricated in a standard 90 nm CMOS process and includes specially designed ESD protection on all mm-wave pads. With a 1.2 V supply the chip consumes 170 mW while transmitting 10 dBm and 138 mW while receiving. Data transmission up to 5 Gb/s on each...
Space diversity technique is an attractive solution for improving quality in wireless links. The objectives of this paper are to investigate the impact of bit error rate on the number of users and the SNR for space time block coded MIMO Rayleigh fading channels. Diversity is a technique used to combat multipath-fading. Space Diversity is a technique in which multiple numbers of antennas are used at...
