Optimal Spatial Sub-channel Resources Allocation Mechanism for Sustainable Bit Rate Wireless Conduits
In a wireless LAN environment, the algorithm can be used to build a multiple antenna system that not only increases bandwidth but also maintain a constant bit rate pipe. The scheme can be implemented in other wireless networks such as 3G.
University researchers have developed an optimal algorithm that optimizes the transmitting power and bits-per-symbol allocation to each of the transmitting antennas in a multiple-input-multiple-output wireless system, so that an overall constant bit rate can be maintained with minimal power consumption. A Leaky Bucket-based power budget algorithm is also devised to smooth out total power allocation among channel burst periods.
