Abstract

Heterogeneous network concept is going to be utilized in the fifth generation mobile communication systems in order to enhance both network throughput and user throughput. Many techniques have been investigated to increase the throughput. However, the techniques are easily degraded with many causes. Performance degradation could be avoided with assistance of some side information such as location of a terminal and Doppler frequency. If Doppler frequency is known before the signal transmission, throughput reduction can be alleviated by selecting modulation schemes with lower cardinality. This paper proposes Doppler frequency estimation technique using overlap frequency domain equalization and the optimum FDE weight which is derived for the proposed estimation technique. The proposed estimation technique with the proposed FDE weight attains better estimation performance than that with the conventional MMSE weight.
