An Improved Sphere-Packing Bound for Finite-Length Codes Over Symmetric Memoryless Channels
This paper derives an improved sphere-packing (ISP) bound for finite-length error-correcting codes whose transmission takes place over symmetric memoryless channels, and the codes...

On the Outage Capacity of a Practical Decoder Accounting for Channel Estimation Inaccuracies
—The optimal decoder achieving the outage capacity under imperfect channel estimation is investigated. First, by searching into the family of nearest neighbor decoders, which can...

Concavity of Mutual Information Rate for Input-Restricted Finite-State Memoryless Channels at High SNR
We consider a finite-state memoryless channel with i.i.d. channel state and the input Markov process supported on a mixing finite-type constraint. We discuss the asymptotic behavio...

Error Exponents for the Gaussian Channel With Active Noisy Feedback
We study the best exponential decay in the blocklength of the probability of error that can be achieved in the transmission of a single bit over the Gaussian channel with an activ...

Improved Channel Estimation in OFDM Systems with Synchronization Errors and Back-Off
— In Orthogonal Frequency Division Multiplexing (OFDM) systems, synchronization errors in the receiver cause a linear phase rotation at the output of the Discrete Fourier Transfo...
