In this paper, a new Belief Propagation (BP) decoding algorithm named Piggybacking Belief Propagation (PBP) decoding algorithm is proposed for rateless codes based on repeat-accumulate (RA) structu
This paper proposes a pilot subcarrier allocation approach for OFDM waveforms, which enables construction of phase-noise estimate with high efficiency and low overhead in non-iterative manner.
In this paper, we investigate pilot allocation problem in two-tier time division duplex (TDD) heterogeneous network (HetNet) with mMIMO.
Pilot contamination due to the pilot reuse in adjacent cells is a very serious problem in time-division duplex (TDD) based massive multi-input multiple-output (MIMO) system.
We analyze the effects of pilot assisted channel estimation on achievable data rates (lower bound on information capacity) over a frequency at time-varying channel.
This paper considers a multi-cell multiple antenna system with precoding at the base stations for downlink transmission.
This paper considers a multi-cell multiple antenna system with precoding used at the base stations for downlink transmission.
This paper considers the pilot contamination problem in multi-cell massive MIMO systems.
Massive MIMO provides great improvements in spectral efficiency, by coherent combining over a large antenna array and by spatial multiplexing of many users.
