Millimeter wave (mmW) communication has emerged as a promising component of the access link for 5G cellular systems. In order to overcome the higher free-space path loss at these frequencies, high gain, and therefore highly directional, antennas are being proposed at both ends of the link. Furthermore, in order to maintain a mobile connection with an acceptable quality of service (QOS), these highly...
Abstract- Millimeter wave (mm wave) communication has emerged as a promising component of 5G cellular systems. The large losses in the Friis equation (due to the implied small apertures of mm wave antennas) suggest that high gain antennas are required. The high gain also implies steerability is required. Arrays of patch antennas are one possible low cost solution, but each array has a limited angular...
Abstract- Millimeter wave (mmW) frequencies are considered to be indispensable for next generation wireless systems, both cellular and Wi-Fi, primarily due to the large amounts of spectrum available in these bands. However, the higher frequency-dependent path loss at these frequencies needs to be overcome by the use of high-gain directional antenna arrays at both transmitter and receiver. Due to the...
Automatic Gain Control (AGC) system performance generally depends on the ability to accurately estimate receive signal power. The initial gain setting may be set high to ensure that low power signals can be detected. As the Variable Gain Amplifier (VGA) resides before the Analog to Digital Converter (ADC), there is a potential for heavy saturation at the output of the ADC, where this estimation is...
It has been predicted that the recent explosive growth in wireless data traffic will continue for the foreseeable future. To date, attempts to address this explosive growth have included increasing base station density through smaller cells, and to a lesser extent, by improving spectral efficiency using close-to-capacity channel coding and MIMO techniques. Providing further capacity and coverage improvements...
