A Joint Power and Rate Allocation Scheme for MMSE Receiver in WCDMA Systems

  • 摘要: 該文針對(duì)3GPP WCDMA系統(tǒng)的反向鏈路,提出了一種基于MMSE接收機(jī)的功率和數(shù)據(jù)速率相結(jié)合的控制算法。該算法可以保證用戶在達(dá)到目標(biāo)信干比的同時(shí),減小平均發(fā)射功率、加快收斂速度,從而提高系統(tǒng)的整體性能。仿真結(jié)果驗(yàn)證了所提出方案的正確性和優(yōu)化算法的有效性。采用該文提出的算法,與MMSE功率控制算法比較,系統(tǒng)容量可增加近10%,而收斂速度可提高30%左右。
