Multiband Real-Time Coherent Optical OFDM Reception up to 110 Gb/s with 600-km Transmission

open access: yesIEEE Photonics Journal, 2010
We demonstrate field-programmable gate array (FPGA)-based multiband orthogonal frequency-division multiplexing (OFDM) signal reception after 600-km standard single-mode fiber (SSMF) transmission and 400-ps differential-group delay (DGD) at 110-Gb/s.

Rapid Prototyping of Field Programmable Gate Array-Based Discrete Cosine Transform Approximations

open access: yesEURASIP Journal on Advances in Signal Processing, 2003
A method for the rapid design of field programmable gate array (FPGA)-based discrete cosine transform (DCT) approximations is presented that can be used to control the coding gain, mean square error (MSE), quantization noise, hardware cost, and power ...

Research on near-field focusing algorithm of reconfigurable reflect-array

open access: yesThe Journal of Engineering, 2019
In this study, the near-field beam focusing algorithm of reconfigurable reflect array for security imaging application is proposed. The proposed near-field focusing algorithm is based on classic array method, which is usually adopted for far-field ...

Field-programmable gate array (FPGA)-based designed using VHDL hardware description language transmission performance analysis of binary phase shift keying (BPSK) and quadrature phase shift Keying (QPSK) modulators

open access: yes, 2013
Binary phase shift keying (BPSK) and quadrature phase shift Keying (QPSK)modulation techniques are often proposed for satellite communications and band-limited communication channels; however, both modulations are important in high speed data ...

Field Programmable Gate Arrays with Hardwired Networks on Chip [PDF]

open access: yes, 2012
Technology down-scaling and platform-based designs have enforced a number of application and architecture trends for system-on-chip (SOC) designs. A modern SOC is now a multi-functional machine that can execute a large number of complex applications by using tens or even hundreds of intellectual properties (IPs).
