Downlink channel estimation for LTE OFDMA system under radio environment

The 3rd generation partnership project (3GPP) long term evolution (LTE) project is designed for high speed data rate, higher spectral efficiency, improved services, and lower latency as well as high-capacity voice support. LTE uses orthogonal frequency division multiplexing access (OFDMA) scheme for the downlink and single carrier frequency division multiple access (SCFDMA) in uplink. Main chal...

Channel Estimation methods with low complexity for 3GPP/LTE

OFDM based pilots channel estimation methods with processing into the transform domain appear attractive owing to their capacity to highly reduce the noise component effect. However, in current OFDM systems, null subcarriers are placed at the edge of the spectrum in order to assure isolation from interfering signals in neighboring frequency bands; and the presence of these null carriers may lea...

Channel Estimation for Lte Uplink System by Perceptron Neural Network

In this paper, a channel estimator using neural network is presented for Long Term Evolution (LTE) uplink. This paper considers multiuser SC-FDMA uplink transmissions with doubly selective channels. This channel estimation method uses knowledge of pilot channel properties to estimate the unknown channel response at non-pilot sub-carriers. First, the neural network estimator learns to adapt to t...

Channel Estimation for Lte Downlink

3GPP LTE is the evolution of the UMTS in response to ever‐increasing demands for high quality multimedia services according to users’ expectations. Since downlink is always an important factor in coverage and capacity aspects, special attention has been given in selecting technologies for LTE downlink. Novel technologies such as orthogonal frequency division multiplexing (OFDM) and multiple ...
