Short Packets over Block-Memoryless Fading Channels: Pilot-Assisted or Noncoherent Transmission? [PDF]
, 2017 We present nonasymptotic upper and lower bounds on the maximum coding rate achievable when transmitting short packets over a Rician memoryless block-fading channel for a given requirement on the packet error probability.

Error-free transmission of microring-modulated BPSK
Optics Express, 2012 We demonstrate the generation of error-free binary-phase-shift-keyed (BPSK) data at 5 Gb/s using a silicon microring modulator. The microring-modulated BPSK signal is propagated at fiber lengths up to 80 km, maintaining error-free performance, while demonstrating resilience to chromatic dispersion. Bit-error-rate measurements and eye diagrams show near

Analysis of IEEE 802.11N-like transmission techniques with and without prior CSI for video applications [PDF]
, 2007 Previous research into MIMO systems has focused little on optimisation for video transmission. In terms of multimedia transmission, spatial multiplexing (SM) is commonly proposed as the most suitable MIMO technique.

Experimental Quantum Error-Free Transmission
, 2010 Error-free transmission (EFT) of quantum information is a crucial ingredient in quantum communication network. To overcome the unavoidable decoherence in noisy channel, to date, many efforts have focused on faithfully transmitting one state by consuming large numbers of synchronized ancillary states.

Explores for the source of the gears in traditional Japanese clock (Wadokei)
Nihon Kikai Gakkai ronbunshu, 2017 The purpose of this study is to understand the nature of one of the oldest gears used in traditional Japanese clock. Today's gear manufacturing technology in Japan came mostly from Europe and America, but we do not know exactly, when and how the ...
