Immortal DB is a transaction time database system that is built into a commercial database system rather than being layered on top. This enables it to have performance that is very...
In this paper, a new channel estimation method for OFDM WLAN systems is proposed. This proposal mainly consists of smoothing filtering and decision-directed tracking loop schemes,...
Because changes to the database (DB) and workload occur during a DB system's lifetime, the physical DB design must evolve to sustain good performance. These changes are carri...
This paper presents a 60 GHz direct-conversion transmitter in 65 nm CMOS technology. The power amplifier consists of 4-stage transistors. The circuit model of de-coupling capacitor...
