In this paper, a new RB (Resource Block) adaptive hopping method based on predefined pattern of intra/inter-TTI frequency hopping is proposed for E-UTRA uplink.
Channel estimation has been studied for single-carrier as well as orthogonal frequency division multiplexing (OFDM) systems. The channel is always estimated in ...
Schemes for estimation of channel will be discussed in Chapter 3, while data detection schemes will be further investigated in Chapter 4. Presented below in ...

In this paper, we propose narrowband demodulation reference signal (NDMRS)-assisted transform-domain low-complexity channel estimation algorithms.
In this paper we present a robust channel estimation using neural network for LTE uplink under high selectivity. The principle of this method is to use the ...
Ali et al. studied the DFT-based channel estimation in [20] for the uplink NB-IoT systems, depending on random sorting least square (RS-LS) ...
In this paper, we propose an improved DFT-based channel estimation scheme that tries to clean the reference signals in the time domain before being used for ...
ABSTRACT This paper deals with generalized discrete Fourier transform—spread—orthogonal fre- quency division multiplexing (G-DFT-s-OFDM) waveforms, ...
Two critical issues in OFDMA uplink transmissions are: frequency/timing synchronization and channel estimation. Sim- ilar to orthogonal frequency-division ...
An algorithm for iterative channel estimation using soft feedback for LTE uplink is proposed. The algorithm has low complexity compared to MMSE estimation.
