Bipolar optical pulse coding for performance enhancement in BOTDA sensors.
A pump signal based on bipolar pulse coding and single-sideband suppressed-carried (SSB-SC) modulation is proposed for Brillouin optical time-domain analysis (BOTDA) sensors. Making a sequential use of the Brillouin gain and loss spectra, the technique is experimentally validated using bipolar complementary-correlation Golay codes along a 100 km-long fiber and 2 m spatial resolution, fully reso...
متن کاملChannel Estimation Technique for MIMO-OFDM over Fast Fading Channels
A channel estimation method for multiple input multiple output (MIMO)-OFDM with fast fading channels is proposed to increase estimation quality and reduce the computational complexity. Specifically, we use a space-time correlation between channel coefficients, and compensate the ICI term. Since ICI compensation can be obtained without any pilot symbols for target OFDM block, our proposal is pra...
متن کاملEnhanced Adaptive Channel Estimation Technique for MIMO-OFDM Wireless Systems
Multiple Input Multiple Output (MIMO) in combination with Orthogonal Frequency Division Multiplexing (OFDM) can provide spectrally efficient and ISI free communication. Channel estimation is of great importance in order to recover the signal at the receiver side. Therefore accurate channel state information is essential for proper detection and decoding in MIMO-OFDM wireless systems. To estimat...
متن کاملSNR Estimation for Pilot-assisted Frequency-domain MMSE Channel Estimation
Abstract— The bit error rate (BER) performance of DS-CDMA in a frequency-selective fading channel can be significantly improved by the use of frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion. Accurate estimation of the channel transfer function and the signal-to-noise power ratio (SNR) are necessary for MMSE-FDE. Direct application of pilot-assisted channe...
متن کاملAn Improved SNR Estimation Algorithm for Asymmetric Pulse-Shaped Signals
The split-symbol moment estimation (SSME) algorithm is a conventional method to estimate the signal-to-noise ratio (SNR) in communication systems for M-ary phase shift keying signals. However, the conventional SSME is based on the assumption of symmetric pulse-shaping waveforms, and becomes no longer proper when the shaping pulse is asymmetric. In this paper, we propose a modified SSME algorith...
