Ray Tracing Methods for Correcting Chromatic Aberrations in Imaging Systems

open access: yesInternational Journal of Optics, 2014
The correction of chromatic aberrations is typically performed using aberration formulas or by using real ray tracing. While the use of aberration formulas might be effective for some simple optical systems, it has limitations for complex and fast ...

Packetization schemes for forward error correction in Internet video streaming [PDF]

open access: yes, 2003
In this work, our focus is on video streaming applications with relatively strict delay constraints; for such applications, forward error correction (FEC) is the preferred channel coding technique to recover from packet losses.

TCM, TTCM, BICM and BICM-ID Assisted MMSE Multi-User Detected SDMA-OFDM Using Walsh-Hadamard Spreading

open access: yes, 2004
Space Division Multiple Access (SDMA) aided Orthogonal Frequency Division Multiplexing (OFDM) systems assisted by efficient Multi-User Detection (MUD) techniques have recently attracted intensive research interests. Forward Error Correction (FEC) schemes

Near-capacity FEC codes for non-regenerative MIMO-aided relays

open access: yes
In this contribution, we derive the Discrete-inputContinuous-output Memoryless Channel (DCMC) capacity of the non-regenerative Multiple-Input Multiple-Output (MIMO) relay channel, when the source-to-destination link is inferior and hence considered ...
