GaAs MESFETs with 1micron gate length were fabricated on InP substrates, after growth of the heteroepitaxial material by MOCVD.

Recently, there has been an increased interest in the use of the time-delay estimation (TDE) technique to locate and track acoustic sources in a reverberant environment.

For cellular systems, the performance improvements due to half- duplex low-power relays as compared to a no relay baseline are evaluated here via simulation.

This paper discusses retransmission approaches to improve the throughput performance of Hybrid-ARQ (HARQ) schemes in a point-to-point single user 3rd Generation Partnership Project (3GPP) Long Term

The full characteristics for two high-concentration erbium-doped fibers are reported.

This study evaluates the performance of an optical receiver for BPSK signals in the presence of noise originating from the photodetectors and the phase fluctuations of the optical sources.

An expanded effort is underway to support the evolution of the UMTS standard to meet the rapidly developing needs associated with wireless Internet applications.

This paper proposes and analyzes the performance of a hybrid selective repeat (SR)/multicopy (MC) automatic repeat request (ARQ) scheme to transmit fragmented internet protocol (IP) packets.

It is expected that 5G systems will bring a great increase of the system data rate, which motivates the key role of massive MIMO cellular solutions operating in mmWave bands.

The use of massive MIMO for communication at millimeter-Wave (mmW) frequency bands has become a key enabler to meet the data rate demands of the upcoming fifth generation (5G) cellular systems.
