The random access (RA) procedure in LTE systems is essential for the machine-type
communication (MTC) in space information networks (SIN). By using the RA procedure, the …

In this article, a novel random pre-coding (RPC) based random access (RA) scheme is
proposed to improve the system performance in the Internet of Things-oriented satellite …

In the context of satellite communications, random access methods can significantly
increase throughput and reduce latency over the network. The recent random access …

In this paper, a multiuser space-time line code (MU-STLC) scheme is newly designed that
concurrently delivers multiple STLC signals to multiple users, and a preprocessing matrix for …

In this paper, interference cancellation (IC) schemes are compared with the inverse channel
detection scheme for space-time block coded multi-rate multi-user systems. One of the …

In this paper, interference cancellation (IC) schemes are compared with the inverse channel
detection scheme for space-time block coded multi-rate multi-user systems. One of the …

The present random access (RA) scheme in terrestrial LTE (T-LTE) cannot be applied in LTE-
satellite system, for the remarkable miss detection probability caused by large difference of …

In LTE downlink systems with a high frequency reuse factor, inter-cell interference has been
viewed as a predominant factor limiting system performance. Therefore, we develop an …

In the LTE system, uplink synchronization can be established through the random access
channel, by which timing and frequency offsets between transceivers can be estimated and …

In this paper, an iterative interference cancellation (IIC) scheme is proposed for space-time
block coded (STBC) multirate multiuser systems. The proposed IIC scheme is based on …
