This paper considers low-complexity transmit beamforming schemes for signal-to-interference-plus- noise ratio (SINR) balancing problem in the Gaussian multiple-input single-output multi-receiver wiretap channel (MISO-MRWC). The formulated max-min-fair problem are shown to be non-convex. To overcome the computational complexity, we develop the leakage-based and zero forcing (ZF) based beamforming algorithms...
This letter presents a coded modulation scheme for indoor visible light communication (VLC), which is based on the recently proposed coding scheme called block Markov superposition transmission (BMST). As the bandwidth of a single light-emitting-diode (LED) light is limited, we use parallel LED wicks to transmit simultaneously multiple coded bit-streams, resembling a multiple access system. At the...
When packed loss caused by bit error occurs in the data transmission of IP network, one should retransmit the corrupted data to avoid information loss. However, this will take more damage for those business in which retransmission is difficult to realize or will limit the performance of system. In order to reduce this damage, this paper studied the checksum restriction mechanism of the IPv4 header...
