Improved LDPC code structure and concatenation rules for IEEE 802.11n systems, providing two code sets per rate, one longer codeword and one shorter codeword. The longer codeword length is determined by the system parameters, while the shorter codeword length is ⅓ of the longer codeword length. A LDPC concatenation rule is provided, wherein a maximum of one extra OFDM symbol is added in padding in order to reduce the code set granularity. In order to provide improved code performance, more bits are shortened compared with puncturing, by transmitting the extra OFDM symbol. Further, all the required puncturing and shortening bits are distributed across all codewords. This scheme provides a preferred tradeoff between code complexity and over-the-air efficiency.

The invention provides a Fabry-Perot interferometric sensor based on a photonic crystal fiber and a manufacturing method thereof. The sensor is composed of a conventional communication single-mode fiber and a solid photonic crystal fiber, wherein the conventional communication single-mode fiber and the solid photonic crystal fiber are welded by using a certain welding method. Because air holes ona cladding of the photonic crystal fiber collapse, an air cavity (namely, an F-P cavity) is formed between the two fibers, and the two end faces (namely, the front and rear surfaces of the air cavity) of the photonic crystal fiber and the single-mode fiber are two reflecting surfaces of the F-P cavity. The solid photonic crystal fiber is made of a single material, and does not cause the mismatching of thermal expansion coefficients of materials in the process of temperature variation, thereby ensuring that the influence of temperature variation on the interferometric sensor is small; in the manufacturing process, only a fiber cutting and welding process is used, therefore, the preparation process is simple; by using the sensor, high-fineness and high-contrast interference fringes can be obtained, therefore, the sensor has a great application potential in large-capacity and quasi-distributed sensing systems; and the sensor is in an all-fiber structure, and has the advantages of small volume, good robustness and low cost.

The present invention provides methods and an infrastructure for performing repetitive data protection and a corresponding restore of data for block oriented data objects comprising several indexed segments. For implementing the invention, timestamps t_k are set by a timer k. Only the first data modification of a segment is recorded, after a timestamp t_k has been set, by storing the old data contents of said segment together with the segment index j and said timestamp t_k as undo-log block in a first journal j₀, before overwriting said segment with the modified new data. Besides, said undo-log blocks are transmitted to N journals j_i for storing redundant undo-log information, with N>1 and i=0, . . . , N−1. According to the present invention for each journal j_i journal-specific timestamps t_k/i are generated, so that each journal j_i is written for a different set of timestamps t_k/i.
