20080225689 | Orthogonal frequency division multiplexing having tones with overlaid data and pilot symbols - In one embodiment, an OFDM transmitter generates sets of frequency-domain data symbols from a stream of digital data. For each set of frequency-domain data symbols generated, the transmitter generates a corresponding set of frequency-domain pilot symbols. Each corresponding set of data symbols and pilot symbols are then multiplexed onto a set of frequency tones, such that, at least one tone is occupied by both a data symbol and a pilot symbol. For each tone having both a pilot symbol and data symbol, the pilot symbol and data symbol are added together to form an overlaid data and pilot (ODP) tone. Each set of tones having at least one ODP tone is then transmitted to an inverse fast Fourier transform (IFFT) processor that transforms each set of tones into an ODP OFDM symbol. Each ODP OFDM symbol is then prepared for transmission using digital-to-analog conversion, cyclic prefix insertion, and RF modulation. | 09-18-2008 |

20090077330 | MODIFIED BRANCH METRIC CALCULATOR TO REDUCE INTERLEAVER MEMORY AND IMPROVE PERFORMANCE IN A FIXED-POINT TURBO DECODER - A turbo decoder that calculates alpha, beta and gamma (branch metric) values does not normalize the branch metric but instead applies the normalization factor to the newly calculated extrinsic values before writing them to interleaving memory, resulting in use of less memory than in prior turbo decoders. A compensating factor is applied when the extrinsics are read from interleaving memory. The absence of normalization in the gamma calculation not only conserves memory but also enhances decoder sensitivity. | 03-19-2009 |

20150309774 | METHOD AND DEVICE FOR CHANGING OBJECTS IN A HUMAN-MACHINE INTERFACE DEVICE - When a programmer creates an object for use in a display screen of a human-machine interface device of a programmable system, at least some of the properties of the object are associated with a variable quantity. The programmer determines the property or properties for which the corresponding variable quantity is reassignable and which are fixed, by carrying out a setting operation, and creating an association record identifying which property or properties have a reassignable variable quantity. The object may then be stored in a library and transferred to the memory of the human-machine interface device. If a subsequent programmer wants to re-use the object by reassigning the variable quantity of one or more of the properties of the object, the association record is used to determine the property or properties for which the corresponding variable quantity is reassignable. | 10-29-2015 |
