Devices for shaping and processing of signals based on known varieties of digital amplitude-
phase modulation are considered. Their disadvantages are exposed during realization of …

In wireless communications, the wireless channels may exhibit frequency-selectivity and
time-variability, and channel coefficients may have large and small scale fadings. All of …

Computation offloading enables energy-limited mobile devices to expand the range of
applications that they can execute. When multiple devices each seek to execute a latency …

Semi-definite relaxation (SDR) detector has been demonstrated to be successful in
approaching maximum likelihood (ML) performance while the time complexity is only …

Semi-definite relaxation (SDR) has demonstrated the capability of approaching maximum-
likelihood (ML) performance. In this work, we first develop a new SDR-based detector that …

In this work, we develop a new iterative turbo receiver for LDPC-coded multi-antenna
systems based on semidefinite relaxation (SDR). For a classical turbo receiver, forward error …
