Achievable Rate Regions Using Novel Location Assisted Coding (LAC)
, 2017 The recent increase in number of wireless devices has been driven by the growing markets of smart homes and the Internet of Things (IoT). As a result, expanding and/or efficient utilization of the radio frequency (RF) spectrum is critical to accommodate such an increase in wireless bandwidth. Alternatively, recent free-space optical (FSO) communication

Cognitive interference channel: achievable rate region and power allocation
IET Communications, 2015 In this study, the authors consider a state‐dependent two user interference channel. The two users sharing the spectrum are assumed to be cognitive and each user has a non‐causal access to the signal from the other user. For this channel model, an achievable rate region is established for both discrete memoryless model and Gaussian channel.

Error Performance of Channel Coding in Random Access Communication
, 2010 A new channel coding approach was proposed in [1] for random multiple access communication over the discrete-time memoryless channel. The coding approach allows users to choose their communication rates independently without sharing the rate information ...

Achievable Rate Region of Quantized Broadcast and MAC Channels
, 2011 In this paper, we study the achievable rate region of Gaussian multiuser channels with the messages transmitted being from finite input alphabets and the outputs being {\em quantized at the receiver}. In particular, we focus on the achievable rate region of $i)$ Gaussian broadcast channel (GBC) and $ii)$ Gaussian multiple access channel (GMAC).

Secure Transmission for Downlink NOMA Visible Light Communication Networks
IEEE Access, 2019 In this paper, we consider the two key problems in the physical-layer security of nonorthogonal multiple access (NOMA) visible light communication (VLC) networks: investigating a closed-form achievable security rate and studying the optimal security ...

Transmission Rank Selection for Opportunistic Beamforming with Quality of Service Constraints
, 2014 In this paper, we consider a multi-cell multi-user MISO broadcast channel. The system operates according to the opportunistic beamforming framework in a multi-cell environment with variable number of transmit beams (may alternatively be referred as the ...

Tongxin xuebao, 2012 In a two-way relay system where two nodes exchange information via a half-duplex relay,the achievable data rates of both directions are limited by the weaker link.When the two-way channel is asymmetric due to relay positioning or channel fading,the sum ...

Capacity region of the 3 receiver state dependent multilevel BC with noncausal state information
ICT Express, 2017 We consider a three receiver state dependent multilevel broadcast channel (BC), where the state information is known non-causally at the encoder as well as all the decoders.
