摘要 提出了一种自适应的V-BLASTOFDM系统,并提出了一种有记忆的可变步长的自适应分配算法。与传统的算法相比,加快了算法的收敛速度。仿真结果表明,该系统与无自适应比特功率分配的系统相比,性能有显著提高。 This paper proposed an adaptive V-BLAST OFDM system and introduced a new adaptive algorithm with changed step size coefficient. Simulation results show the adaptive algorithm is efficient, and this system also outperforms the traditional one in BER performance.
