The use of multiple-antenna techniques in downlink wireless networks increases overall throughput by exploiting degrees of freedom in the spatial domain.
In a given area, since power is controlled, the chances of overlapping the sensing ranges of sources and next hop relay nodes or destination node decreases, so it enhances the probability of concurrent transmission and hence an increased overall throughput.
Fully exploiting these interfaces has motivated researchers to propose numerous solutions that aggregate their available bandwidths to increase overall throughput and satisfy the end-user's growing data demand.
This leads to an increased overall system throughput.
In addition, simultaneous data transmission can be achieved via channel switching and MIMO-based data transmission, thereby increasing the overall throughput of the network.
Extensive simulations demonstrate that our scheme does better than the conventional PRB allocation scheme (of assigning PRBs based on their data rate demand), by increasing the overall throughput and energy efficiency of the network.
This results in maximum number of vacant PU channels being discovered in shorter period of time, consequently, increasing the overall throughput by leaving extended time for data transmission and improving energy efficiency.
Rate adaptation is a technique that enables the selection of the most suitable error-correction coding rate according to the real-time channel quality, therefore increasing the overall throughput.
In particular, high-throughput two-color single-molecule detection would allow speeding up the acquisition of single-molecule FRET data, enabling the study of slow varying equilibria [ 41] or simply increasing the overall throughput of the powerful but still relatively tedious single-molecule fluorescence approaches [ 1, 42].
Today, WMNs support MCMR scenarios which has further increased the overall throughput of the network.
