Sentence examples for requirements spectrum from inspiring English sources

The requirements spectrum sensing algorithms have to meet are quite demanding, e.g., the IEEE 802.22 standard for cognitive wireless regional area networks [2] states that an SU receiver should be able to reliably detect a primary user (PU) signal at a signal-to-noise ratio (SNR) of −22 dB.

Finally, the hardware requirements where spectrum sensing for CR applications require operation over wide bands that need wideband RF sections as well as high sampling rate and consequently high resolution analog-to-digital converters with large dynamic range and high-speed signal processors [26].

The contribution is the derivation of the optimal pricing for transmit power minimization under minimum utility requirements and spectrum sharing constraints.

These paper-based guidelines contained a short definition, diagnostic requirements, the spectrum of causative pathogens and empiric therapy recommendations for every infection.

This requirement makes spectrum sensing a key function in cognitive radio systems.

This paper explores an improved parallel algorithm based on user's requirement of spectrum.

This requirement of spectrum agility has encouraged the study of alternative multicarrier waveforms such as filter bank multicarrier (FBMC) to provide better adjacent channel leakage performance without compromising spectral efficiency [2].

Due to the emerging high demand of broadband service and new applications, wireless networking also has to face the challenge of supporting fast increasing data traffic with the requirement of spectrum and energy utilization efficiency[4].

Universal availability of interfaces   Millimeter-wave frequencies High scalability and capacity High path loss   High frequency reuse Low penetration   Small form factor Line-of-sight requirement   Underutilized spectrum     Point-to-multipoint links  .

Based on the BER requirement, the required power spectrum density (PSD) of the sequence to generate can be obtained to form a PSD template.

However, aiming at maximizing the achievable network throughput leads to tight requirements on cooperative spectrum sensing parameters (e.g., spectrum sensing time and number of cooperating devices).
