Downlink Analysis and Evaluation of Multi-Beam LEO Satellite Communication in Shadowed Rician Channels

  title={Downlink Analysis and Evaluation of Multi-Beam LEO Satellite Communication in Shadowed Rician Channels},
  author={Eunsun Kim and Ian P. Roberts and Jeffrey G. Andrews},
The extension of wide area wireless connectivity to low-earth orbit (LEO) satellite communication systems demands a fresh look at the effects of in-orbit base stations, sky-to-ground propagation, and cell planning. A multi-beam LEO satellite delivers widespread coverage by forming multiple spot beams that tessellate cells over a given region on the surface of the Earth. In doing so, overlapping spot beams introduce interference when delivering downlink concurrently in the same area using the… 



Downlink Analysis of LEO Multi-Beam Satellite Communication in Shadowed Rician Channels

This work characterize the powers of desired and interference signals as received by ground users from such a LEO satellite, and observes that co-cell and crosscell sky-to-ground signals travel along similar paths, whereas terrestrial coand cross-cell signalsTravel along very different paths.

Performance Analysis of Satellite Communication System Under the Shadowed-Rician Fading: A Stochastic Geometry Approach

This paper analytically derive the exact outage probability, and the approximated expression is obtained using the Poisson limit theorem, and proposes an iterative algorithm to obtain near-optimal solutions to solve the system throughput maximization problem.

Throughput and Capacity Evaluation of 5G New Radio Non-Terrestrial Networks with LEO Satellites

This paper analyzes and evaluates the throughput and capacity performance of LEO NTN using 5G NR, and finds that, due to the large cell sizes in the LEONTN, the area capacity density is moderate; the area downlink capacity is moderate.

Beam Coverage Comparison of LEO Satellite Systems Based on User Diversification

A system method to simulate the two satellite system which described by the throughput, delay, access probability, and the sensitivity of beam coverage to user diversification is summarized and discussed.

Dual-Hop Communication Over a Satellite Relay and Shadowed Rician Channels

A dual-hop amplify-and-forward (AF) relaying scheme over shadowed Rician fading channels is investigated, and some useful engineering insights are manifested, such as simplified asymptotic outage performance results, the diversity order, and the impact on the number of antennas at the source and the destination.

The land mobile satellite communication channel-recording, statistics, and channel model

An analog model of the land mobile satellite channel which can readily be used for software and hardware fading simulation is developed and the most important parameter of this model is the time-share of shadowing.

A new simple model for land mobile satellite channels: first- and second-order statistics

A new shadowed Rice (1948) model for land mobile satellite channels, where the amplitude of the line-of-sight is characterized by the Nakagami distribution, provides a similar fit to the experimental data as the well-accepted Loo's (1985) model but with significantly less computational burden.

Sum of Squared Shadowed-Rice Random Variables and its Application to Communication Systems Performance Prediction

The rationale of this paper is to evaluate the distribution of the sum of SR random variables, both for the case of independent as well as correlated LOS components, and to carry out an extensive performance analysis of maximal ratio combining (MRC) detection scheme on SR fading channels.

C-Band Multiple Beam Antennas for Communication Satellites

It is found that the MFB architecture applied in C-band is a more realistic approach when compared to the SFB option, and is the key to get compact feed clusters that can be allocated in large and medium-size platforms.
