حداقل پهنای باند صوتی تئوری لازم برای انتقال دیتای باینری با نرخ 9600 baud ، 4800hz است . چون یک رادیو nbfm معمولی دارای پاسخ فیلتر نشده از صفر تا 8khz است انتقال نرخ بیت 9600 از چنین سیستمی ممکن است . این طرح یک طراحی با کارایی بالا و حالت دوطرفه(full duplex) است که برای بسته هایی که از nbfm رادیویی باند صوتی استفاده می کنند و همچنین ماهواره هایی که با این مشخصات رادیویی سازگار باشند مناسب است...

We consider “virtual” full-duplex relaying by means of half-duplex relays. In this configuration, each relay stage in a multi-hop relaying network is formed by at least two relays, used alternatively in transmit and receive modes, such that while one relay transmits its signal to the next stage, the other relay receives a signal from the previous stage. With such a pipelined scheme, the source ...

The inevitable high bandwidth requirement in the future cellular network has made researchers to come up with revolutionary ideas in recent times. One such idea is the introduction of full-duplex (FD) communication. A FD systems make the simultaneous in-band transceiving feasible, i.e, simultaneous uplink and downlink operation using the same spectrum resources. In recent years, extensive work ...

This paper presents the design and implementation of the first in-band full duplex WiFi-PHY based MIMO radios that practically achieve the theoretical doubling of throughput. Our design solves two fundamental challenges associated with MIMO full duplex: complexity and performance. Our design achieves full duplex with a cancellation design whose complexity scales almost linearly with the number ...

The device in conventional half-duplex WiFi networks cannot perform carrier sensing while in data transmission; thus it suffers from long collision duration. To mitigate this problem, this chapter introduces full-duplex (FD) technology into WiFi networks. A novel CSMA/CD protocol design is first presented for singlechannel FD-WiFi, which facilitates continuous carrier sensing and transmission s...

We study a multi-cell multi-user MIMO full-duplex network, where each base station (BS) has multiple antennas with full-duplex capability supporting single-antenna users with either full-duplex or half-duplex radios. We characterize the upand downlink ergodic achievable rates for the case of linear precoders and receivers. The rate analysis includes practical constraints such as imperfect selfi...

Recently the in-band full-duplex in wireless communication has evolved into a mature technology since the self-interference cancellation technique is able to support fullduplex capability. Moreover, some researchers focus on the full-duplex media access control (MAC) protocol design for wireless local area networks (WLANs). However, it is assumed that all the node have full-duplex capability in...
