摘要: 數(shù)字模擬混合預(yù)編碼可以用較少的射頻逼近全數(shù)字預(yù)編碼的性能，可以用來解決毫米波大規(guī)模MIMO系統(tǒng)中由于射頻鏈路過多造成的硬件損耗和校準(zhǔn)問題。為解決傳統(tǒng)混合預(yù)編碼結(jié)構(gòu)難以實現(xiàn)的缺點，該文的混合預(yù)編碼研究基于一種簡單的固定子連接結(jié)構(gòu)。推導(dǎo)了系統(tǒng)可達速率最大，模擬預(yù)編碼矩陣應(yīng)滿足的條件，從而將混合預(yù)編碼矩陣設(shè)計問題轉(zhuǎn)化為優(yōu)化問題。采用鳥群算法(BSA)解決此優(yōu)化問題，求得最優(yōu)的預(yù)編碼矩陣。針對模擬移相器分辨率有限的情況，提出一種直接量化的解決方案和一種基于改進的離散BSA的解決方案。仿真結(jié)果表明，所提算法能夠基于簡單結(jié)構(gòu)實現(xiàn)較好的性能；移相器分辨率有限情況下，所提的兩種解決方案都是有效的，且基于離散BSA的方案在分辨率較低時性能更優(yōu)。

Abstract: The digital and analogue Hybrid Precoding (HP) is able to keep the performance close to that of the fully digital precoding with reduced Radio Frequency (RF) chains. In a millimeter wave massive MIMO system, the HP can be used to overcome the undesired hardware cost and calibration workload caused by the excessive RFs. Considering that the conventional HP structure is not practical, the research is based on a simple fixed sub-connection structure. The condition that the analogue precoding matrix should meet to maximize the sum achievable rate is deduced, so that the design of the analogue precoding matrix is transformed into an optimization problem. The optimal analogue precoding matrix is obtained by using Bird Swarm Algorithm (BSA). Considering that finite resolution phase shifters are used, a straightforward quantization solution and an improved discrete BSA based solution are proposed. The simulation results show that the proposed algorithm can achieve good performance based on simple structure. While using finite resolution phase shifter, both of the proposed solutions are effective, furthermore, the solution based on the discrete BSA can get better performance while the resolution is low. -
