چکیده
Matching filter (MF)-free digital multiplexed (DFM) single sideband (SSB) OFDM intensity modulation and direct detection (IMDD) dual-channel transmissions of 51.25Gbit/s over 25km SSMFs are experimentally demonstrated. It is shown that both transmission system impairments characteristic variations can only lead to <1dB performance degradations. Compared with the MF-free DFM-based double (DSB) technique, SSB technique has a similar receiver DSP complexity provides almost twice maximum signal capacity. When compared conventional DFM incorporating dedicated shaping matching pair for each channel, present achieves 10-fold reduction 7.82Gbit/s additional throughput. We demonstrate these throughput advantages by modelling measurement.

Sorting-free digital median filter for SOCs
In this work, we propose a new median-finding algorithm which computes the median value in an input list of integers on-the-fly, without any data-sorting operations. We present a complete digital CMOS implementation, associated timing diagrams, and a formal mathematical proof, which show the overall average number of clock cycles for median-finding to be linearly proportional to the input lengt...
متن کاملDigital Filter Design Using Computer Algebra Systems
Digital filter design can be performed very efficiently using modern computer tools. The drawback of the numeric-based tools is that they usually generate a tremendous amount of numeric data, and the user might easily lose insight into the phenomenon being investigated. The computer algebra systems successfully overcome some problems encountered in the traditional numeric-only approach. In this...
متن کاملExperimental Evaluation of Interference from MB-OFDM UWB Systems to Narrowband Wireless Digital Transmission Systems
Multi-band orthogonal frequency-division multipleaccess (MB-OFDM) is one of the UWB technologies that realize wireless personal network (WPAN). In this paper, we experimentally investigated the interference from MBOFDM signal to narrowband QPSK digital transmission system. The bit error rate (BER) performance of the narrowband QPSK system under the interference of UWB signal was evaluated, assu...
متن کاملTheoretical and experimental investigation of compatible SSB modulation for single channel long-distance optical OFDM transmission.
We present the first experimental demonstration of compatible single-sideband (compatible-SSB) modulated OFDM optical system at 11.1Gb/s data rate for long distance transmission over 675 km uncompensated standard single-mode fiber. Compatible-SSB modulation employing a simple dual-drive Mach-Zehnder modulator (MZM) in the transmitter and direct-detection at the receiver provides an OFDM system ...
متن کاملChannel Estimation for SCM-OFDM Systems by Modified Kalman Filter
In this paper, the problem of channel estimation for superposition coded modulation-orthogonal frequency division multiplexing (SCM-OFDM) systems over frequency selective channels is investigated. Assuming that the path delays are known, a new channel estimator based on modified Kalman filter algorithms is introduced for the estimation of the multipath Rayleigh channel complex gains (CG). In th...
