The first terminal includes a matrix calculation portion that calculates a transmission weight matrix suitable for transmitting data from the first terminal to the second terminal, and a matrix multiplication portion that multiplies a first data stream and a second data stream by the transmission weight matrix, the first data stream being transmitted from the first terminal to the second terminal, and the second data stream being transmitted from the first terminal to the third terminal. | 2010-04-15 |
20100091898 | RECOVERY OF DATA FROM A MULTI CARRIER SIGNAL - In an embodiment, a multi-carrier signal (e.g., an OFDM signal) is received over a channel. First indicators of interference and channel response at a carrier frequency of the signal are determined and compared. If the first indicator of the interference has a relationship to the first indicator of the channel response, then a data value transmitted at the carrier frequency is recovered from a data value received at the carrier frequency according to a first algorithm. If, however, the first indicator of the interference does not have a first relationship to the first indicator of the channel response, then second indicators of interference and the channel response at the carrier frequency are determined and compared. If the second indicator of the interference has a second relationship to the second indicator of the channel response, then the data value transmitted at the carrier frequency is recovered from the data value received at the carrier frequency according to a second algorithm. Because first and second data-recovery algorithms may be faster than a conventional data-recovery algorithm, recovering one or more data values with the first or second algorithms may increase the speed at which data is recovered from a multicarrier signal as compared to using a conventional data-recovery algorithm exclusively. | 2010-04-15 |

A direct approach to achieve this minimization results in complexity which grows exponentially with T, where T is the size of the input. The iterative process avoids this complexity by converging on the MAP solution through repeated maximization of the auxiliary function. | 2010-04-15 |

The wireless communication device comprises an encryption unit for encrypting transmission data with an encryption key, a decoding unit for decoding received data with the encryption key, a key replacing unit for generating a new encryption key to update an encryption key to be used in the encryption unit and the decoding unit to the new encryption key, and a key storing unit for storing the encryption key before being updated. The decoding unit decodes a received data with use of the old encryption key stored in the key storing unit when the received data cannot be decoded with use of the newly updated encryption key. | 2010-04-15 |
20100091994 | Encryption Validation Systems and Related Methods and Computer Program Products for Verifying the Validity of an Encryption Keystore - Methods for verifying the operability of an encryption keystore are provided. Pursuant to these methods, the keystore may be periodically checked to verify that it has each required CA authority. If one or more of the required CA authorities are missing from the keystore, then an alert is automatically issued. The methods may also include periodically checking the keystore to verify that the keystore has each required digital certificate and that each digital certificate operates properly. The methods can further include periodically checking the keystore to determine if any of the required CA authorities and/or digital certificates have expired and/or are set to expire within a predetermined time period. Related encryption validation systems and computer program products are also provided. | 2010-04-15 |
20100091995 | SIMPLE PROTOCOL FOR TANGIBLE SECURITY - The claimed subject matter provides systems and/or methods that effectuate a simple protocol for tangible security on mobile devices. The system can include devices that generate sets of keys and associated secret identifiers, employs the one or more keys to encrypt a secret and utilizes the identifiers and encryptions of the secret to populate a table associated with a security token device that is used in conjunction with a mobile device to release sensitive information persisted on the mobile device for user selected purposes. | 2010-04-15 |
20100091996 | METHOD AND APPARATUS FOR INPUT OF CODED IMAGE DATA - An image input device which includes a means for inputting image data, a memory for storing a secret information and an operator for carrying out an operation by using the image data and the secret information. | 2010-04-15 |
