Title: Decoding of data received from one source by several receivers
Inventor: ACHIR MOUNIR
IPC: H03M13/11
Filed: 2012-12-03
Abstract: In a decoder using systematic block error correcting (e.g. LDPC) codes, a controller unit (220) receives from each of several receivers (212-1 to 212-3) a partial data block comprising a set of data symbols along with a subset of parity symbols received at each of the receivers. For each received partial data block, the controller unit generates its own subset of parity symbols and compares the generated subsets with the respective received subsets of parity symbols, to determine a reliability measure for the received data symbols. One of the sets of data symbols is selected based on the reliability measures. In another embodiment, the controller unit generates a complete set of parity symbols for each received set of data symbols, substitutes a respective received subset of parity symbols in each generated set, and again performs a reliability measure to select a set of data symbols.

Title: Retractable petal collet backup for a subterranean seal
Inventor: BISHOP DAVID S
IPC: E21B33/12
Filed: 2011-07-26
Abstract: A high expansion plug has multiple sealing elements and an extrusion barrier system that uses overlapping petals in a stack of rings. When setting the plug, the petals are elastically moved toward a surrounding tubular wall in an elastic deformation between a housing that surrounds the mandrel and a tapered ring on the mandrel. That sandwich controls the amount of deformation and allows a potential energy force to be stored in the petals that allows them to return toward their initial position when the set of the plug is released and the seals are allowed to relax and extend axially as they shrink radially. The plug can then be removed without milling. Expansions in the order of 25% of the initial seal dimension are contemplated.

Title: Data transmission optimisation method and apparatus
Inventor: GURCAN MUSTAFA
IPC: H04L25/02
Filed: 2013-06-28
Abstract: The invention applies to a multiple input multiple output (MIMO) transmission system or a system involving a plurality of parallel single input single output (SISO) channels. A transmitter divides an input signal into K streams and spreads each stream using a different spreading code. The streams are then transmitted using multiple transmit antennas. Claim 1 requires that symbols are spread on a symbol by symbol basis every symbol period such that each signal is spread using a respective spreading sequence. One embodiment is concerned with determining, at a receiver, the signal which was transmitted based on the received signal, a channel matrix and the spreading sequences used at the transmitter. This may involve multiplying the received signal with the inverse of a covariance matrix, the Hermitian of the channel matrix and the Hermitian of a normalization matrix. The covariance matrix and the channel normalization matrix are calculated from the channel matrix and a matrix of spreading sequences. In a second embodiment, for each received symbol a system value indicative of a SNR associated with the symbols respective spreading sequence is determined. A data rate for transmission of symbols is determined by averaging the system values of a plurality of symbols.
