چکیده
This report summarize some results from [1, 2, 3] in multiple-access channel (MAC) with user cooperative diversity. Also, a brief discussion over the relationship between this model and other channels, (e.g. MAC with feedback, relay channel), is presented and expected to inspire further discussion on the class as well as help to gain some insight over this particular model.

Performance analysis of coded cooperation diversity
In a multi-user environment, coded cooperation creates transmit diversity for small mobiles (e.g. handsets) that cannot support more than one antenna. Coded cooperation allows these mobiles to share their antennas via a simple and effective coding method. In this work we present an analytical methodology for evaluating the performance of coded cooperation. We develop tight bounds for bit and bl...
متن کاملUser Cooperation with Punctured Turbo Codes
In wireless network transmission, a recently introduced form of spatial diversity, known as user cooperation diversity is an effective way to overcome deep fading. Cooperative users share their antennas and other resources to create a virtual array through distributed transmission and signal processing. In particular, the user cooperation technique is capable of providing sufficient diversity g...
متن کاملReed Solomon Coded Cooperation Scheme in Mobile Communication Networks and Application
Coded cooperative communication technique utilizes single antenna mobiles in a multiuser environment that share their antennas and incorporates channel coding in order to achieve transmit diversity. This thesis presents a new coded cooperation scheme based on Reed Solomon (RS) codes. The RS codes are very effective in correcting random symbol errors and random burst errors over wireless fading ...
متن کاملDedicated-Relay vs. User Cooperation in Time-Duplexed Multiaccess Networks
The performance of user cooperation that results when users forward packets for each other in a multiaccess network is compared to that of dedicated-relay cooperation which results from using a dedicated wireless relay when the users do not cooperate. Using the total transmit and processing power consumed at all nodes as a cost metric, the outage probabilities achieved by dynamic decode-and-for...
متن کاملUser cooperation diversity. Part I. System description
—Mobile users' data rate and quality of service are limited by the fact that, within the duration of any given call, they experience severe variations in signal attenuation, thereby necessitating the use of some type of diversity. In this two-part paper, we propose a new form of spatial diversity, in which diversity gains are achieved via the cooperation of mobile users. Part I describes the us...
متن کاملRelay vs. User Cooperation in Time-Duplexed Multiaccess Networks
The performance of user-cooperation in a multi-access network is compared to that of using a wireless relay. Using the total transmit and processing power consumed at all nodes as a cost metric, the outage probabilities achieved by dynamic decode-and-forward (DDF) and amplify-and-forward (AF) are compared for the two networks. A geometry-inclusive high signal-to-noise ratio (SNR) outage analysi...
