In the alternative scenario (Figure 1b), both 802.11n APs and FAPs have a total bandwidth of 20 MHz with different frequency reuse pattern 1 and 3, respectively.
The alternative scenario is defined in the body of investigation, in which both FAPs and 802.11n APs have a total bandwidth of 20 MHz with different frequency reuse pattern 1 and 3, respectively.
At every time point, each country will have some non-zero percentage of the total bandwidth quanta.
In the previous equation Bavail is the bandwidth still available for new reservations, Bcommitted is the total bandwidth that the relevant node has committed to forward on behalf of other nodes, Bown is the traffic that the node itself will generate, and Boverheard is the amount of bandwidth committed in reservations that the node has overheard.
Let and represent the total bandwidth and coherence bandwidth, respectively.
This segment can have contiguous or non-contiguous spectra with a total bandwidth of W Hz (where W < B), which can be divided into K equal frequency slots.
Each sub-band has a 3 dB-bandwidth B i and the total bandwidth of s a (t) is B. We define the baseband frequency f i as the sub-carrier frequency of the sub-band i.
The user link has a total available bandwidth of 500 MHz; color schemes with frequency reuse factor equal to 3 and 1 were studied, corresponding to 166 and 500 MHz available bandwidth per beam, respectively.
In Figure 3, the multi-band filters are arrays of band-pass filters having the −3 dB bandwidth BW N, where BW is the total bandwidth of the OFDM signal.
Extensive simulations have been performed and the results have shown that, compared to existing algorithms, the proposed method achieves better performance in terms of minimizing both total bandwidth and the maximum individual bandwidth.
