Abstract: A method of multicasting a data file. The method includes transmitting a notification on an upcoming multicast transmission to a plurality of receivers (20) designated to receive the multicast transmission, tuning by at least one of the plurality of receivers (20) to one or more multicast channels, responsive to the notification, transmitting a data file, from a data server (42), on the one or more multicast channels, without the data server (42) receiving acknowledgements from the receivers (20) on whether they received the notification, determining receivers (20) designated to receive the multicast transmission that did not receive at least a portion of the data file; and attempting to deliver the data file to the determined receivers (20).

Abstract: A method of preparing data for transmission. The method includes providing a block of data, generating a plurality of first dimension code words including first dimension forward error correction FEC elements, the elements of each code word may be used interchangeably to reconstruct a data portion of the block corresponding to the code word, defining a plurality of second dimension source words formed of the generated elements and generating for at least two of the defined second dimension source words, different numbers of parity elements.

Abstract: Disclosed are a method, device and system for enhancing reception of a communication signal in a wireless communication network. According to some embodiments of the present invention, a supplemental receiver transmits a communication augmentation signal to a mobile device. The supplemental receiver is also adapted to receive from the mobile device a signal including audio content.

Abstract: A wireless receiver device including a wireless network interface and a processor configured to manage reception of data files through the network interface. The processor additionally is configured to determine network or wireless receiver device conditions and to delay reception of blocks of a file, responsive to the determined conditions meeting specific requirements, although the determined conditions allow reception of a block without the delay.

Abstract: A method of transmitting data. The method includes receiving data to be transmitted to a receiver, determining information on the structure of the received data, segmenting the received data into segments, in a manner determined responsive to the determined structure information and transmitting the segments to the receiver.

Abstract: A method of multicasting data. The method includes providing a data block for multicasting, generating a plurality of segments that represent the data block, such that a receiver needs to receive fewer than all the generated segments in order to reconstruct the data block, encrypting at least a portion of the generated segments, so as to generate encrypted data units encrypted with a plurality of different keys or encryption methods and transmitting the encrypted data units over one or more multicast channels.

Abstract: In accordance with the preferred embodiments of the present invention, a method (400) and a base station (140) for providing a plurality of transmit diversity protocols in a wireless communication system are described herein. In particular, the base station (140) generates a first signal based on a first data stream with a first pilot and a second data stream with a second pilot. That is, the first signal includes the first and second pilots. The first pilot is based on a first orthogonal code and the second pilot is based on a second orthogonal code. The base station (140) generates a second signal based on the first data stream with the first pilot and the second data stream with the second pilot such that the second signal including the first and second pilots is diverse relative to the first signal. Further, the base station (140) phase-shift modulates the first signal to produce a phase-shift modulated signal.
