| Abstract: | Channel estimation plays a very important role in OFDM communication system. With the introduction and analysis of traditional LS estimation, the author recommends an ameliorated LS estimation criterion, on which a mathematical model is created and stimulated. The stimulation results demonstrate that with lower BER the improved LS estimation, compared with traditional LS, can decrease the effects of estimation error. |
