摘要
研究了在MIMO系统中存在码间干扰时,基于Kalman和PDA基础上的多用户检测方法。通过论述可以看出此算法的复杂度与最大似然编码的方法相比较,只是多项式级的。计算机仿真试验表明,将Kalman和PDA结合应用到MIMO系统的多用户检测中,与球形译码相比较能够更好的减少误码率。
A multiuser detection is proposed based on Kalman filter and PDA algorithm under the condition that MIMO system has strong ISI (intersymbol interference). The complexity of Kalman - PDA is only polynomial time low in contrast to an ML solution. It can be seen from the simulation results that the new algorithm based on Kalman filter and PDA can eliminate intersymbol interference efficiently.
