Channel Estimation Using LS and MMSE Estimators

Shakuntala Chouhan

Abstract :

This paper focuses on the channel estimation techniques that are based on the block-type pilot arrangement. Once we establish reliable and practical channel estimation schemes for this type of pilot arrangement. In wireless OFDM transmission using pilot carriers and compare the bit error rate performance by using MMSE and LSE algorithms. Thus comb type pilots provide better resistance to fast fading channels. Also comb type pilot arrangement is sensitive to frequency when compå to block type arrangement.
