| Abstract: |
| The fixed bvoadband wireless access(BWA) standard IEEE 802.16 and a DFE equalization algorithm : exponential weighting recursive least squares(RLS)are introduced,the principle of Training/Decision-Directed channel equalization technique is described.Finally,according to a special(IEEE 802.16) test channel model,the performance of two equalization algorithms LMS and RLS is simulated,and it is found that the RLS algorithm is superior to LMS algorithm. |
