tailieunhanh - Format (Channel coding )
Signal processing plays a key role in the optimization of disc capacity together with system margins of the optical drive. For the new format, new modulation codes have been designed for the rewritable version (parity-preserving code) and the read-only version (combi-code). For bit-detection in the rewritable format, a nonrecursive algorithm with PRML-like performance is devised. Finally, a new ECC code, called the picket code, was designed in order to cope with multiple long burst errors, on top of the usual random errors of the channel. | BÀI 3 Format Channel coding Dàng Lê Khoa Email danglekhoa@ dlkhoa@ Facuty of Electronics Telecommunications HCMUNS 1 Facuty of Electronics Telecommunications HCMUNS 2 Digital Communications I Modulation and Coding Course Period 3 - 2007 Catharina Logothetis Lecture 9 Facuty of Electronics Telecommunications .
