This paper describes a 24GHz CMOS RF transceiver for car radar applications. The transceiver consists of 4-channel receiver array and 1-channel transmitter. The prototype is designed by standard RF CMOS 0.13-μm technology. The simulated receiver gain is 30dB and simulated tramsmitted output power is 15dBm at 24GHz.

This paper addresses CDMA transceiver using direct sequence spread spectrum and includes real time signal processing for scrambling of spread spectrum signal, and descrambling the signal at the receiver using the same pseudo-random code. The simulation of the entire DS-CDMA transceiver system has been implemented using MATLAB, which provides real time audio input to the system.

A universal BiCMOS low-voltage-swing transceiver (driver/receiver) with low on-chip power consumption is reported. Using a 3.3 V supply, the novel transceiver can drive/receive signals from several low-voltage-swing transceivers with termination voltages ranging from 5 V down to 2 V and frequencies well above 1 GHz. Measured results of test circuits fabricated in 0.8m BiCMOS technology are also...

Abstract—In this paper, a design of H.263 based wireless video transceiver is presented for wireless camera system. It uses standard WIFI transceiver and the covering area is up to 100m. Furthermore the standard H.263 video encoding technique is used for video compression since wireless video transmitter is unable to transmit high capacity raw data in real time and the implemented system is cap...
