Minimum Bit-Error Rate Design for Space-Time Equalisation-Based Multiuser Detection

open access: yes, 2006
A novel minimum bit-error rate (MBER) space–time equalization (STE)-based multiuser detector (MUD) is proposed for multiple-receive-antenna-assisted space-division multiple-access systems. It is shown that the MBER-STE-aided MUD significantly outperforms

An error floor in tone calibrated transmission [PDF]

open access: yes
Use of a low level pilot tone has been shown to eliminate the error floor in fading channels. This paper demonstrates that non-idealities in the receiver's pilot tone filter cause reappearance of the error floor. It also presents the bit error rate (BER)

BER analysis of high-speed OFDM systems in the presence of time-interleaved analog-to-digital converter's offset mismatch [PDF]

open access: yes, 2015
Time-interleaved analog-to-digital converters (TI-ADCs) are widely used for multi-Gigabit orthogonal frequency division multiplexing (OFDM) systems because of their attractive high sampling rate and high resolution. However, mismatch between the parallel

In-Line-Test of Variability and Bit-Error-Rate of HfOx-Based Resistive Memory

open access: yes, 2015
Spatial and temporal variability of HfOx-based resistive random access memory (RRAM) are investigated for manufacturing and product designs. Manufacturing variability is characterized at different levels including lots, wafers, and chips. Bit-error-rate (

Design and Implementation of a Chaotic Scheme in Additive White Gaussian Noise Channel

open access: yesJournal of Computer Networks and Communications, 2016
A new chaotic scheme named Flipped Chaotic On-Off Keying (FCOOK) is proposed for binary transmission. In FCOOK, the low correlation value between the stationary signal and its mirrored version is utilized.

Differential spatial modulation for high-rate transmission systems

open access: yesEURASIP Journal on Wireless Communications and Networking, 2018
This paper introduces a new differential spatial modulation (DSM) scheme which subsumes both the previously introduced DSM and high-rate spatial modulation (HR-SM) for wireless multiple input multiple output (MIMO) transmission. By combining the codeword

Block Markov superposition transmission over turbulence channels in outdoor optical wireless communication

open access: yesTongxin xuebao, 2017
Based on the equivalent genie-aided system,the bit-error rate of the block Markov superposition transmission system was analyzed and the union bound of the bit-error rate of the genie-aided system was derived.When the bit-error rate was extremely low at ...
