Sentence examples for cognitive broadband from inspiring English sources

As shown in Figure 15, under the NLOS scenarios (train speed of 240 km/h), by employing the advanced Doppler compensation algorithm based on the dedicated REM for high-speed rail (marked as Algorithm 2 in this figure), the cognitive broadband mobile communication system has significant performance gain against the approach without Doppler compensation.

In the following section, we first review the key challenges encountered by the high-speed rail broadband mobile communications, and then bring forward the system architecture of the proposed cognitive broadband mobile communication systems.

With the feedback on link performance, cognitive broadband mobile communication systems can update or fine-tune the channel parameters while the high-speed train moves along the given course repetitively.

This paper proposes a dedicated sensing receiver architecture that addresses some challenges of broadband sensing in Cognitive Radios.

Dynamic spectrum access is a promising technique designed to meet the challenge of rapidly growing demands for broadband access in cognitive radio networks.

One application of cognitive radios is to provide broadband wireless access (BWA) in the licensed TV bands on a secondary access basis.

To evaluate the performance of a cognitive high-speed rail broadband mobile communication system, dynamically changing channel conditions, including both LOS and non-LOS (NLOS) scenarios, need to be simulated.

Specific research directions include linear-yet-efficient high-power (watt-class) millimeter-wave amplifiers in CMOS, CMOS-based terahertz circuits and systems, and broadband reconfigurable RF transceivers for cognitive and software-defined radio.

As a case study example, TD-LTE (i.e., the TDD version of LTE) standard is adopted for the broadband mobile data-pipe between the cognitive wireless gateway on the train and the track-side base station.

Owing to its several attractive features, OFDMA has been envisaged for possible implementation in future-generation wireless networks, e.g., 3GPP-long term evolution [1], cognitive radio networks [2], and IEEE 802.20 mobile broadband wireless access [3].

For higher SPL broadband sound masking, the cognitive test scores were similar within the different talker numbers.
