Generalized Transmission Scheme for Mimo Y Channel

Abstract

Abstract-This paper proposes a novel scheme for a multi-way communication where users combine bi-directional multi-pair messages exchange with multi-directional multi-pair exchange. Particularly, we focus on the system where multiple users have multiple antennas exchange both private and common messages with each other. In this scheme, we can use simple zero forcing combined with successive network code decoding enables all user to decipher the encryption message from the relay despite the fact that they all have different self-information which they use as a key.

Dynamic Macromolecular Material Design—The Versatility of Cyclodextrin‐Based Host–Guest Chemistry

“…[63] Liu and co-workers presented as upramolecular polymer formed from aC Dt rimer.T wo permethyl-b-CDs were connected to a b-CD,a nd ap orphyrin with multiple guest groups was added to form as upramolecular polymer. [70] Interestingly, combinations of CD complexes with other host/guest motifs in an orthogonal fashion were also examined, for example, with cucurbit [8]uril [71] or bis(sulfonate)calix [4]arene. [72] Wei and co-workers reported ab lock copolymer consisting of blocks of supramolecular polymer and PEG.…”

Effect of nano‐titanium nitride on thermal insulating and flame‐retardant performances of phenolic foam

“…35 Unfortunately, most of researches focused on investigating the thermal conductivity of PF at only one temperature point. 24,29 As we know, PFs are applied in diverse applications, such as civil construction, 36 passenger and military aircrafts, marines and electronic fields 28 at complex temperature conditions. Therefore, it is extremely important to study the thermal conductivities of PFs over a wide range of temperature, which are evidently significant to the practical applications of PF.…”

MIMO relay channel signal transmission in transformed signal subspace

“…The scheme in [13] which proposes a novel hybrid transmission scheme for special scenario: multiple users exchange bi-directional multi-pair signals and multi-directional multi-pair signals simultaneously with each other via a relay with multiple antennas. Especially, each user simultaneously sends one multicast shared signals for all users and multiple unicast specified signals for target users.…”

“…The authors in [15] consider the new case N > 2M which has a broader range of dimension constraint compared to the existing SSA schemes [8][9][10][11][12][13][14]. Recently, the authors in [16] proposed a generalized signal alignment (GSA) based transmission scheme for MIMO two-way X relay channels.…”

“…Then, the SSA scheme applies to the generalized K -user Y channel in [11] and the X relay channel [12]. Recently, Wang et al [13] proposed a novel scheme where users combine bi-directional multi-pair messages exchange with multidirectional multi-pair exchange with SSA and successive network code. It is proved that the SSA significantly increases this network throughput.…”
