Correlation Receivers Minimizing Intersymbol Interference

open access: yes, 1962
The problem considered here is that of binary pulse communication operating in a white noise environment -wherein interfering signal pulses are generated by any of the following causes t (1) A signaling rate larger than channel bandwidths, causing pulse spill over into succeeding bands. (2) Go-channel interference or cross talk on carrier systems.

Performance measurement results for a 220 Mbps QPPM optical communication receiver with an EG/G Slik APD [PDF]

open access: yes
The performance of a 220 Mbps quaternary pulse position modulation (QPPM) optical communication receiver with a 'Slik' silicon avalanche photodiode (APD) and a wideband transimpedance preamplifier in a small hybrid circuit module was measured.

Interblock-interference-free precoding using square-root decomposition for faster-than-Nyquist signaling

open access: yesDigital Communications and Networks
Precodings using square-root decomposition, including Cholesky and G-To-Minus-Half (GTMH) precodings, are promising for eliminating the Faster-Than-Nyquist (FTN)-induced Intersymbol-Interference (ISI).

Efficient Sequence Detection of Multicarrier Transmissions over Doubly Dispersive Channels

open access: yesEURASIP Journal on Advances in Signal Processing, 2006
We propose a high-spectral-efficiency multicarrier system for communication over the doubly dispersive (DD) channel which yields very low frame error rate (FER), with quadratic (in the frame length) receiver complexity.

Subband Array Implementations for Space-Time Adaptive Processing

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
Intersymbol interference (ISI) and cochannel interference (CCI) are two primary sources of signal impairment in mobile communications. In order to suppress both ISI and CCI, space-time adaptive processing (STAP) has been shown to be effective in ...
