The pervasive use of wireless sensors in a growing spectrum of human activities reinforces the need for devices with low energy dissipation. In this work, coded communication between a couple of wireless sensor devices is considered as a method to reduce the dissipated energy per transmitted bit with respect to uncoded communication. Different Low Density Parity Check (LDPC) codes are considere...

Content caching is a widely studied technique aimed to reduce the network load imposed by data transmission during peak time while ensuring users' quality of experience. It has been shown that when there common link between caches and server, delivering contents via coded scheme can significantly improve performance over conventional caching. However, finding optimal content placement challenge...

corrective feedback (cf) and its different types have long absorbed many scholars and practitioners. as ellis (2009) mentioned some experimental studies need to be carefully designed to discover the relative effectiveness of each of these cf techniques. the goal of this qualitative study was to discover whether the employment of different cf strategies could bring about an attitudinal shift. to...

We consider broadcasting a block of packets to multiple wireless receivers under random packet erasures using instantly decodable network coding (IDNC). The sender first broadcasts each packet uncoded once, then generates coded packets according to receivers’ feedback about their missing packets. We focus on strict IDNC (S-IDNC), where each coded packet includes at most one missing packet of ev...

Introduction: Space-time codes with antenna subset selection has been a subject of intense research recently [1–6]. In [1] and [4], the error performance of the Alamouti scheme with transmit antenna selection was investigated and it was shown that a full diversity order can be achieved, as if all the transmit antennas were used. In most of the published papers dealing with transmit antenna sele...

Caching enables reduction of peak backhaul load in modern wireless systems by allowing popular files to be pre-fetched and stored locally and closer to the network edge. With the shift in paradigm from homogeneous to heterogeneous cellular networks, data offloading to small cell base stations (sBS) has garnered recent attention. Caching at the sBS can help avoid bottlenecks in the capacity limi...
