摘要： A modulator device for converting digital data into modulation of an optical signal includes an electronic input for receiving an input data word of N bits and an electrically controllable modulator for modulating the intensity of an optical signal, the modulator including M actuating electrodes where M≧N. An electrode actuating device, most preferably a digital-to-digital converter, operates actuating electrodes so that at least one electrode is actuated as a function of values of more than one bit of the input data word. According to an alternative, or supplementary, aspect of the invention, the set of electrodes includes at least one electrode having an effective area which is not interrelated to others of the set by factors of two. In one preferred implementation, a Mach-Zehnder modulator also provides phase modulation to give QAM functionality. Another implementation employs a semiconductor laser.

摘要： A syndrome assisted iterative decoder (173) uses iterative processing to decode an input sequence. A syndrome-assisted decoder (216), which may operate independently of a soft-output decoder, provides a stopping algorithm for the soft output decoder (240). When the syndromes s0 and s1 generated for sequence v0 and v1, respectively, both equal 0, the soft output decoder is finished decoding the sequence of data. Additionally, the syndrome-assisted decoder can generate a modified error trellis used by the soft output decoder whereby the soft-output decoder operates on a simplified trellis providing improved decoder performance.

摘要： Soft output decoding of signals represented by a trellis of block length N divided into windows includes a step of decoding a forward recursion to a location that is I sections from the beginning of the window. An optimum state is detected at the end of the forward recursion. A backward recursion is performed from the determined state at the end of the window back to the beginning of the window to define a set of known backward recursion state metrics. Soft outputs are calculated during the backward recursion using the stored forward recursion state metrics, the backward recursion state metrics, and branch metrics at each state.

摘要： A method for bounded distance decoding of symbols received in transmission when the original symbols belonged to a Block code featuring series of symbols forming legitimate codewords whose metric distance from the received transmission is measured in Square Euclidean Distance (SED), when the maximum number of errors per word is upward bound by d-1; in which the Block code can be divided into subsets which will each define the entire codeword; and in which the maximum number of errors in at least one subset is one. The method includes dividing the received symbols into a number of blocks per codeword and decoding each block separately and simultaneously with regard to a maximum of one error present in each block. The solution of the decoder is the legitimate codeword with the lowest overall metric distance (SED) from the received transmission.
