Abstract: The BER is used as a parameter for evaluating the performance of an optical transmission system. Performance of optical systems is also defined by the Q factor, which uniquely determines the BER in the absence of distortion. The measurements are effected in a point of operation of the channel which gives a value of interest for the Q factor. To this end, the optical SNR is lowered by adding noise over the information signal. A distortion-free Q (Q DF) and a back-to-back Q (Q BB) are determined in the same operating point of the system. The distortion penalty for transmitter-receiver pair may be determined by comparing Q DF to Q BB The noise loading technique will allow to investigate if equalizing. The value of OSNRs at the output of a particular system results in equalizing the noise margin in that systems or not.

Abstract: Dans un résonateur pouvant fonctionner dans des modes supérieurs, notamment un guide d'ondes coaxial, différents modes d'oscillation d'un champ électromagnétique sont injectés et superposés les uns aux autres. Le champ d'excitation à modes mixtes, ainsi obtenu, est utilisé pour exciter une antenne de préférence biconique. La caractéristique de rayonnement azimutale de l'onde électromagnétique émise par l'antenne présente la même dépendance que la répartition de champ azimutale dans le résonateur. En particulier, la caractéristique de rayonnement présente, dans le cas d'un champ d'excitation anisotrope azimutal, des orientations privilégiées dans l'émission azimutale. Une modification supplémentaire des relations de phase ou d'amplitude entre les modes des champs électromagnétiques injectés entraîne un changement d'orientation de l'émission maximale de l'onde électromagnétique.

Title: Turbo product code decoder
Inventor: HEWITT ERIC
IPC: H03M13/29
Filed: 1999-09-27
Granted: 2008-02-05
Abstract: The present invention is a turbo product code decoder capable of decoding multi-dimensional coding schemes. The decoder may be implemented in any digital communication system capable of receiving an encoded stream of data. The decoder is configured for receiving soft decision values. The decoder iteratively decodes the data by generating new soft difference values for each axis-iteration of decoding. These soft difference values represent the change in soft decision values after each axis-iteration. The soft difference values from each axis-iteration are then summed with the original soft decision values in decoding each of the other axis. After any full iteration - i.e. after all axis dimensions have been decoded one full time, the previous difference values for any axis are discarded when that axis is decoded in subsequent iterations. Accordingly, the same information is not continuously fed into the decoder during each subsequent iteration, thereby decreasing the likelihood of error and offering an improvement over prior decoders. Moreove r, using unique nearest neighbor computation logic, the decoder of the present invention is able to generate valid nearest neighbors more efficiently without requiring the use of a look-up table, thereby reducing the amount of time required to decode. Finally, the decoder of the present invention utilizes four decoders arranged in parallel along with a unique memory array accessing scheme such that multipl e rows or columns may be decoded at the same time, thereby increasing the data throughput time of the decoder over prior turbo product code decoders.
