Research On Method Of PUCCH Channel Estimation Based On UCI Separate Coding
نویسندگان
چکیده
channel quality indicator and hybrid automatic repeat –request acknowledgement are important feedback information in system of 3GPP LTE, adopted joint or separate coding when transmitted via Physical uplink control channel. When uplink control information adopted type of joint coding, performance of channel estimation will decline and the number of reference signal will decrease because the ACK/NAK bits are embedded in one of the CQI reference signals. A program for uplink channel estimation is proposed for this issue. Simulation results show the effectiveness of the algorithm, which has been applied to TD-LTE wireless integrated test instrument.

Multiplexing Periodic CSI with HARQ-ACK on PUCCH Format 3 in LTE-A
In order to avoid dropping the periodic CSI report frequently in case of collision between a periodic CSI report and HARQ-ACK feedback in LTE-Advanced system, this paper gives two coding schemes for multiplexing periodic CSI (Channel State Information) with HARQ-ACK (Hybrid Automatic Repeat request Acknowledgement) feedback on PUCCH (Physical Up Control Channel) format 3. The result of simulati...

Channel estimation is an essential task to fully exploit the advantages of the massive MIMO systems. In this paper, we propose a semi-blind downlink channel estimation method for massive MIMO system. We suggest a new modeling for the channel matrix subspace. Based on the low-rankness property, we have prposed an algorithm to estimate the channel matrix subspace. In the next step, using o...
متن کاملAn efficient secure channel coding scheme based on polar codes
In this paper, we propose a new framework for joint encryption encoding scheme based on polar codes, namely efficient and secure joint secret key encryption channel coding scheme. The issue of using new coding structure, i.e. polar codes in Rao-Nam (RN) like schemes is addressed. Cryptanalysis methods show that the proposed scheme has an acceptable level of security with a relatively smaller ke...
متن کاملImproved Channel Estimation Algorithms based on a Proposed Signal Model for PUCCH Format 3 in LTE-A
SORTD (Space Orthogonal-Resource Transmit Diversity) has already become a better way of transmit diversity for PUCCH format 3 in LTE-A [1]. SORTD technology lies in the characteristic that each antenna port transmits signal by using different cyclic shift [2] to make orthogonal each other. Using the SORTD’s feature of incoherence in different antennas, this paper proposes a special form of sign...
متن کاملImproved Channel Estimation for DVB-T2 Systems by Utilizing Side Information on OFDM Sparse Channel Estimation
The second generation of digital video broadcasting (DVB-T2) standard utilizes orthogonal frequency division multiplexing (OFDM) system to reduce and to compensate the channel effects by utilizing its estimation. Since wireless channels are inherently sparse, it is possible to utilize sparse representation (SR) methods to estimate the channel. In addition to sparsity feature of the channel, the...
