Design and Analysis of Dual-stream Beam-forming for LTE-R System
摘要
Abstract
In order to improve the spectrum efficiency and reduce the co-channel interference in high-speed railway quick-changing channel environment, a PMI-quantized dual-stream beam-forming method is proposed with a view to maximize effective power of transmitted signals. The method makes dual-stream beam-forming more efficient by constructing a weighted codebook applied to high-speed railway and offers rapid searching according to the reciprocal channel estimation information of TDD. Simulation results show that the method reduces the computational complexity of dual-stream beam-forming enormously with very small performance loss compared with the traditional algorithm based on SVD decomposition, and efficient dual-beam-forming can be realized in the LTE-R system downlink.关键词
