Optimum Power and Rate Allocation Strategies for Multiple Access Fading Channels
نویسندگان
چکیده
We obtain the (Shannon) optimal power and rate allocation strategies for the uplink on single cell systems. For an N user system, we show that successive decoding which is independent of channel state is optimal in the Shannon sense. Using this result, we frame a simple N dimensional convex optimization problem, which is solved to obtain optimum power and rate allocation as explicit functions of the channel state.

Power Allocation Strategies in Block-Fading Two-Way Relay Networks
This paper aims at investigating the superiority of power allocation strategies, based on calculus of variations in a point-to-point two-way relay-assisted channel incorporating the amplify and forward strategy. Single and multilayer coding strategies for two cases of having and not having the channel state information (CSI) at the transmitters are studied, respectively. Using the notion of cal...
متن کاملBit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...

We obtain the (Shannon) optimal power and rate allocation strategies for the uplink on single cell systems. For an N user system, we show that successive decoding which is independent of channel state is optimal in the Shannon sense. Using this result, we frame the resource allocation problem as a simple convex problem in N variables. We divide the vectors space formed by all possible channel s...
متن کاملResource allocation for fading multiple-access channels with partial channel state information
Dynamic resource allocation based on the current channel state is a promising strategy to increase the capacity of wireless links. In this paper, the optimum accessing and resource allocation scheme for fading multiple–access channels with partial CSI at the transmitters are found. Partial knowledge of the fading states is a reasonable assumption for systems which provide a low rate feedback ch...
متن کاملNear-optimum transmit power allocation for space– time block encoded wireless communication systems
Space–time block codes (STBCs) allow the diversity provided by multiple-input– multiple-output (MIMO) communication channels to be utilised, thereby increasing the capacity over ergodic fading channels or decreasing the outage probability over non-ergodic fading channels. The authors consider the deployment of orthogonal STBCs in spatially distributed mesh networks where the potentially differe...
