A blind channel estimation technique based on denoising for LTE Downlink and Uplink system [articol]

Abstract

The main purpose of this paper is to introduce a blind channel estimation technique based on denoising for multiple access schemes in 3GPP Long Term Evolution (LTE) technology, which uses Orthogonal Frequency Division Multiple Access (OFDMA) in the Downlink and Single Carrier Frequency Division Multiple Access (SC-FDMA) in the Uplink. The architecture of the proposed technique is presented and its performance is proved for both OFDMA and SCFDMA by computer simulation in term of Bite Error Rate (BER).
