摘要:
In one embodiment, a communications system has a write path and a read path. In the write path, a local/global interleaver interleaves a user data stream, and an error-correction (EC) encoder encodes the user data stream to generate an EC codeword. A local/global de-interleaver de-interleaves the parity bits of the EC codeword, and both the original un-interleaved user data and the de-interleaved parity bits are transmitted via a noisy channel. In the read path, a channel detector recovers channel soft-output values corresponding to the codeword. A local/global interleaver interleaves the channel values, and an EC decoder decodes the interleaved values to recover the original codeword generated in the write path. A de-multiplexer de-multiplexes the user data from the parity bits. Then, a local/global de-interleaver de-interleaves the user data to obtain the original sequence of user data that was originally received at the write path.

The present invention relates to a method, an apparatus and a computer program product for sensing and communicating in transmission systems with shared spectrum usage, which may comprise e.g. a cognitive relay system. The communication between a transmitter and a receiver occurs in two transmission phases via the assistance of a relay. Sensing is performed at the transmitter during the second transmission phase, thus overcoming the need for dedicated slots for sensing.

The present invention generally relates to popularity indicators, influence measures, and purchase incentives. More particularly, but not by way of limitation, the present invention relates to assessing and communicating the popularity or relative popularity of objects such as songs, books, documents, pictures, web links, comments, authors, artists, creators, based on either the number of user profiles with whom an object or a reference to an object was shared on one or more social network(s) by web users, or on the number or percentage of social network connections who acted on such a referral. It also relates to measuring the influence of a web user (or group thereof) with regard to a particular object or set of objects by using the number of user profiles with whom the web user (or group thereof) shared the object(s) or a reference(s) thereto on one or more social network(s), and offering commercial incentives based on that measure.

The present invention is directed to, inter alia, a biological reagent that includes a complex having a first GPCR and a second GPCR linked to a G-protein, the linkage between the second GPCR and the G-protein being of a length, which pre-vents productive interaction between the G-protein and the second GPCR, wherein the first GPCR and the second GPCR linked to the G-protein alone are incapable of producing a signal when presented with a ligand. The invention also provides methods of producing such a biological reagent, as well as methods of determining oligomeric GPCR interactions, methods of identifying compounds that have an effect on GPCR oligomers, methods of identifying a compound capable of interacting with GPCR oligomers, methods of identifying a compound having the ability to modulate binding between a GPCR oligomer and its ligand, and methods for evaluating differential G-protein coupling.

摘要:
A method and apparatus for determining location information of a position in a multi-storey building, the method comprising: retrieving observation data comprising observed addresses and corresponding observed received signal strengths of wireless access points detected at the position from a memory; retrieving, for each storey of the building, a radio map comprising a plurality of location points in the respective storey of the building from a database, each location point comprising addresses and corresponding mean received signal strengths of wireless access points detected at the location point and coordinates of the location point; selecting one or more location points comprising the observed addresses from the radio map; determining a storey estimate of the position by calculating a sum probability for each storey of the building, the sum probability being calculated by summing all individual probabilities of each observed address contained in each selected location point in the radio map of the respective storey being detected on the respective storey; and setting the storey estimate as the storey of the building having highest value of the calculated sum probability, wherein each of said individual probabilities is calculated based on the corresponding observed received signal strength of said each observed address in said each selected location point and the corresponding mean received signal strength in said each selected location point containing said each observed address.
