{ "item_title" : "Advanced Digital Signal Processing for Coherent Optical Transmission", "item_author" : [" Zhu Chen "], "item_description" : "The main objective of this book is to investigate computationally-efficient and modulation format-flexible DSP algorithms for fibre channel impairment compensation and performance monitoring in PDM single-carrier coherent optical systems. Novel blind equalization scheme based on frequency domain block processing structure is proposed for PDM-QPSK and PDM-16-QAM systems with single-stage and two-stage convergence process, respectively. Then the combination of training-aided channel estimation and single-step multiple-input-multiple-output (MIMO) frequency domain equalization is presented and discussed. We further investigate the overhead-free training-aided equalization scheme by utilizing implicit training sequence which is carried using a small portion of the signal power. An OSNR monitoring technique based on the statistical moments of the equalized signals is then proposed for in-band OSNR estimation. Finally we address the issue of combining Nyquist matched filtering and linear channel impairment compensation in a single linear MIMO equalizer, which achieves the computationally-efficient receiver's DSP solution for Nyquist-WDM systems.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/3/63/976/086/3639760867_b.jpg", "price_data" : { "retail_price" : "86.29", "online_price" : "86.29", "our_price" : "86.29", "club_price" : "86.29", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
