【摘要】 LS算法是OFDM系统信道估计方法中计算复杂度最低性能最差的方法。根据有限长度h的能量分布,提出了一种改进算法。通过仿真,与LS算法和性能较好的LMMSE比较,验证了改进后的LS算法性能优于最初的LS算法,并可在实际中得到较好的应用。更多还原

【Abstract】 LS algorithm is the lowest complexity and worst performance of channel estimation in OFDM system.According to the energy of finite length impulse response,an improved algorithm is researched.The simulations indicate that the improved LS estimator has better performance than LS estimator compared with LS algorithm and LMMSE algorithm.And it can be used effectively.更多还原
