MINIMAL TOTAL TRANSMIT POWER IN RELAY WIRLESS TRANSISSION NETWORK USING SPECTRAL OPTIMIZATION TECHNIQUE

Abstract

The multi-antenna relay wireless transmission system with AF processing
protocol has received a lot of research attention on the power generation
optimization problems. The SDR technique was used in previous proposals by
vectorizing the pre-decoding matrix and then producing a matrix of secondary
variables that increased the computational complexity. To solve this problem
with large size problems, the number of additional variables needs to be
shortened. Finally, an optimal problem with a smaller complexity than the
proposed SDR technique is proposed. The paper proposes a Spectral optimization
technique to deal directly with the variable matrix to be optimized through
eigenvalue analysis and eigenvectors. The simulation results demonstrate that
the use of SPO optimization technique has brought asymptotic results to SDR
technology at different SINR threshold levels.
