Sentence examples for multiple relays with from inspiring English sources

First, two-way communication scheme of a MIMO relay network consists of multiple relays with multiple antennas is firstly considered.

Recently the most general extension, i.e., a multiple-antenna source and a multiple-antenna destination aided by multiple relays with multiple antennas, is considered in [16, 17].

Thus we focus on this simplified system where there are multiple relays with a single antenna while the source and the destination have multiple antennas.

It has been proven that the use of multiple relays with different selection methods can enhance the diversity and the performance [13 23].

As a simpler case, if multiple relays with a single antenna are distributed geographically in a network, the matrix formed by all relay gains should be a diagonal matrix when full cooperation is not possible.

where v ¯ rd t + 2 = v ¯ sr t + v ¯ rr t + 1 + v rd t + 2 is the total noise at the destination, which contains the filtered noise contributions from the multiple relays, with v ¯ sr t = H rd J H rr G v sr, v ¯ rr t + 1 = H rd J v rr t + 1, v rr t + 1 ≐ v rr ( 1 ) T t + 1, …, v rr ( R 2 ) T t + 1 T ∈ C N 2 × 1, v sr t ≐ v sr ( 1 ) T t, …, v sr ( R 1 ) T t T ∈ C N 1 × 1.

In the context of multi-hop transparent relaying, additional impairments on the end-to-end channel from multiple relaying, with distinct per-hop distributions due to distinct environments, require special attention as it affects the system design and receiver performance.

Cooperation with multiple relays, or relays with multiple antennas have extensively been treated in the wireless literature, cf. e.g., [11, 12] and references therein.

This paper investigates a wireless cooperative relay network with multiple relays communicating with the destination over orthogonal channels.

In a MIMO relay system, communication between source nodes and destination nodes can be assisted by single or multiple relays equipped with multiple antennas.

Multiple relays equipped with dynamic buffers are then introduced in the network, which allows the relays to store data received from the sources and wait until the most appropriate time for transmission.
