Power efficient Transmit/Receive (T/R) Elements for Integrated mm-Wave Phased Arrays
… knowledge (18mW and 26mW power dissipations at receiver (Rx) and transmitter (Tx) front-ends respectively). Rx shows 23 to 25 dB peak gain, 6 to 9.3 dB NF and Tx can deliver upto 7 dBm output power with 18% power efficiency. Moreover, our PS can achieve 5-bit phase resolution with <2 degrees RMS …

Real-time control of a robot using brain activity
… of two computing units: a transmitter (Tx) and a receiver (Rx). Tx will process the EEG signal and send a classification signal to the Rx unit. The receiver processes the signal so that the signal is classified into one of four distinct groups. Once classified, the receiver will transmit a control …

Non-stationary Vehicle-to-Vehicle Channel Characterization
… in its relatively low transmitter (Tx) and receiver (Rx) antenna heights, and that both Tx and Rx and some significant scatterers are all mobile. Given the dynamic nature of the V2V environment, the channel may be statistically non-stationary (NS), and traditional wide-sense stationary …

Wide band TX Leakage Cancellation for FDD Transceivers
… order to separate the transmitter (TX) and the receiver (RX) signals. To avoid RX being saturated and desensitized, the isolation between the TX and RX ports of the duplexer needs to be as large as possible. However, such a duplexer is less desirable for a base station due to its bulky size, …

Designing a dynamic spectrum sharing algorithm between DCS and LTE in the 1800 MHz band: a case study of a mobile telecommunication operator in Zimbabwe
… voice call drops, total carried traffic, and receiver (Rx) signal quality. The simulations revealed a substantial surge in LTE throughput, averaging 62% across both clusters, resulting in an overall increase in LTE traffic by 34%, thanks to DSS implementation. Remarkably, this enhancement in …

MIMO channel modelling and simulation for cellular and mobile-to-mobile
… in M2M systems both the transmitter (Tx) and receiver (Rx) are in motion and often equipped with low elevation antennas. Multiple-input-multiple-output (MIMO) technologies, employing multiple antennas at both the Tx and Rx, have widely been adopted for the third generation (3G) and beyond-3G …

A design technique for geometric optimisation of resonant coil sizes in low to mid frequency inductive power transmission systems.
… coupling between a Transmitter (Tx) and a Receiver (Rx) coil. Maximising the PTE is a key driver for improving the performance of RIPT systems. In a RIPT link the PTE is influenced by three factors: (i) inductive linkage between the Tx and Rx, (ii) terminating circuitry of Tx and Rx sides …

Integrated Wideband Self-Interference Cancellation Techniques for FDD and Full-Duplex Wireless Communication
… cancellation (SIC) circuitry, a low-power receiver, combined with a harmonic-rejection power amplifier (HRPA) are implemented to reduce the transmitter-to-receiver self-interference, and enable full-duplex operation. These techniques were applied towards the realization of a prototype …

Systems and circuits for broadband contactless and wireline transceivers
… to enable feedforward data recovery in the receiver. A novel dual-edge-tracking clock and data recovery loop (DE-CDR) is introduced to retrieve the clock from the received 3-level data stream featuring a fast phase-locking loop (PLL) and a slow delay-locking loop (DLL). The transceiver …
