Polarization Reconfigurable Non-Orthogonal Multiple Access (PR-NOMA) for Next Generation Communication Systems
… reconfigurable NOMA (PR-NOMA). On the transmitter (Tx) antenna side, a combination of the polarization, power transmission and the transmission power allocation coefficient, α, is to be configured and adjusted to work with the combination of the received signals and the polarization at …

Real-time control of a robot using brain activity
… consists of mainly 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 …

Fully Integrated Wireless Power Transfer System For Biomedical Applications
… CMOS process. The receiver is separated from the transmitter (Tx) by 10mm of biological media. The on-chip coil demonstrates a peak WPT efficiency of 1.42% in air, 0.97% efficiency while receiving power through a combined 7mm of 0.2 molar NaCl (with similar conductivity and permittivity as blood) …

Non-stationary Vehicle-to-Vehicle Channel Characterization
… channels specifically 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 …

Power efficient Transmit/Receive (T/R) Elements for Integrated mm-Wave Phased Arrays
… 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 phase error and …

Wide band TX Leakage Cancellation for FDD Transceivers
… a duplexer is needed in 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 …

Two New Applications of Tensors to Machine Learning for Wireless Communications
… with a uniform planar antenna (UPA) array at the transmitter (Tx) whose channel distribution is available through a dataset. Represented as a tensor, the FD-MIMO channel is further decomposed using a tensor decomposition technique to obtain an optimal precoder which is a function of …

MIMO channel modelling and simulation for cellular and mobile-to-mobile
… (F2M) cellular systems, 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 …

A design technique for geometric optimisation of resonant coil sizes in low to mid frequency inductive power transmission systems.
… of magnetic resonance 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 …

Integrated Wideband Self-Interference Cancellation Techniques for FDD and Full-Duplex Wireless Communication
… an extremely challenging problem associated with transmitter self-interference cancellation. To date, two full-duplex chips have been designed, fabricated and tested, each with a self-interference cancellation function. The first IC is an analog full-duplex front-end for Bluetooth (BLE) …

Systems and circuits for broadband contactless and wireline transceivers
… a Tomlinson-Harashima precoding scheme in the transmitter 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 …
