Abstract We consider in this paper the problem of phase offset and copyright Frequency Offset (CFO) estimation for Low-Density Parity-Check (LDPC) coded systems. We propose new blind estimation techniques based on the calculation and minimization of functions of the Log-Likelihood Ratios (LLR) of the syndrome elements obtained according to the parity check matrix of the error-correcti... https://allfixelectricales.shop/product-category/ratchet-wrench/
