Abstract: Methods and devices are disclosed for receiving and detecting sparse data sequences using a message passing algorithm (MPA) with early propagation of belief messages. Such data sequences may be used in wireless communications systems supporting multiple access, such as sparse code multiple access (SCMA) systems. The determination and passing of one or more messages for an edge between a function node and a variable node in a factor graph representation of the system may be performed in serial with determined values available early for subsequent computations. The serial computations may be scheduled based on various factors.

Abstract: A network-wide interference cancellation scheme estimates channel impulse responses related to Self Interference and the Mutual Interference, then reduces both the Self Interference and the Mutual Interference in the receiver of an Full Duplex device. Full Duplex gains may be capitalized upon and translated into system gain. The scheme is based on an extended Multiple-Input-Multiple-Output (MIMO) treatment of the whole Full Duplex network. The network-wide interference cancellation may be seen to be feasible when a unique pilot signal design and training structure are in place network-wide.

Abstract: The complexity of sparse code multiple access (SCMA) decoding can be reduced by pruning codebooks to remove unlikely codewords prior to, or while, performing an iterative message passing algorithm (MPA). The pruned codebook is then used by to perform one or more iterations of MPA processing, thereby reducing the number codeword probabilities that are calculated for the corresponding SCMA layer. The pruned codebook also reduces the computational complexity of calculating codeword probabilities associated with other SCMA layers. The pruned codebook may be “reset” by reinserting the pruned codewords into the codebook after a final hard-decision for a given set of received samples is made, so that the pruning does not affect evaluation of the next set of samples.

Abstract: The invention concerns an electronic housing (100) intended to be fixed under a cover of a manhole, the cover comprising at least a first fixing means and a through cavity, the electronic housing (100) comprising: a shell (102) having a top face, for the or each first fixing means, a second fixing means intended to cooperate with said first fixing means in order to fix said shell (102) under the cover, electronic components comprising a wireless communication module, and a control module intended to change said wireless communication module from an inactive mode to an active mode, said control module comprising a sensor able to react in the presence of a wakeup device, projecting with respect to said top face and intended to be housed in said cavity.

Abstract: A paper dispenser includes a casing for housing a roll of paper, the casing having a front face, with a dispensing nozzle through which the paper is dispensed, wherein the front face has a hatch for access to the inside of the casing, through which a free end of the roll can be extracted.

Abstract: The dispenser according to the invention is a paper dispenser, particularly for toilet paper, comprising a casing (5) for housing a roll (3) of paper, the casing (5) having a front face (8), with a dispensing nozzle (13) through which the paper is unwound sheet by sheet, and means (11) for locking the front face (8) to the casing (5). This dispenser is characterized in that the front face (8) has a hatch (16) for access to the inside of the casing (5), through which the free end (4) of the roll (3) can be extracted. Such a dispenser enables the user to resolve problems of paper jamming inside the casing (5), but without the possibility of stealing the roll (3), while, in all circumstances, leaving the roll in such a form that it remains usable.

Abstract: A modular dispenser of sheet products including an open-ended case (10), a front panel (20), and a rear panel (30) is characterized in that the open-ended case is fitted with first longitudinal ribs (11, 12) by which the front and rear panels are kept in place on the open-ended case. In particular, the open-ended case includes a set of ribs providing the function of guidance, assembly and closing.

Abstract: The invention relates to a dispenser of paper articles, in particular interlocked table napkins, including a receptacle closed by a panel 7 forming the front surface and provided with an opening 71 for the distribution of articles with an edge 73. This dispenser is characterized by the fact that at least a portion of the edge of the opening is extended by a wall element 74 extending outward in relation to the plane of the panel.

Abstract: A dispenser of individual sheets by unwinding from the center of a product in roll form, without a central tube, having a plurality of successive sheets forming a coiled strip, a free end of which projects toward the outside of the roll from the center, of the type including a fixed dispensing nozzle which delimits a passage of frustoconical general shape and which includes a generally vertically oriented cutout to make it easier to introduce the free end of the strip of a roll into the passage, the width of the cutout in the vicinity of the upper orifice of the passage being markedly greater than its width in line with the lower outlet orifice of the nozzle.
