This paper is concerned with channel estimation and data detection for a cellular multi-carrier code division multiple access network using single-hop relaying in the presence of frequency selective fading channels. The proposed expectation-maximization (EM) algorithm was used to jointly estimate both the coefficients of the channel between a relay and a base station and the data. EM algorithm is particularly suited to multicarrier code division multiple access systems because they have multi-carrier signal format. The considered network uses single-hop relaying technique to provide a higher quality transmission to the users with low quality channels. The base station (managing mechanism) gives them an opportunity to send their messages via the users with high quality channels in a time sharing mode. The performance of the proposed EM algorithm, with and without hopping and with cooperative communication technique, was analyzed by a computer simulation, and the results are presented.

“…While it is clear that network coding opportunities in a wireless network significantly depend on the configuration of network parameters [17], [28], [29], the existing studies on random access based wireless networks [16], [17] do not explicitly exploit the interaction between network parameters and network coding (i.e., do not formulate and solve a joint problem).…”

“…Recently, the throughput performance of a two-hop relay network (i.e., three-node network) with network coding is studied in [28], [29]. The authors demonstrate that network coding opportunities significantly depend on the configuration of MAC parameters, although these works are limited to a two-hop relay network.…”

Abstract-We study cross-layer design in random access based fixed wireless multihop networks under a physical interference model. Due to the complexity of the problem, we consider a simple slotted ALOHA medium access control (MAC) protocol for link layer operation. We formulate a joint routing, access probability, and rate allocation optimization problem to determine the optimal max-min throughput of the flows and the optimal configuration of the routing, access probability, and transmission rate parameters in a slotted ALOHA system. We then also adapt this problem to include an XOR-like network coding without opportunistic listening. Both problems are complex non-linear and non-convex.We provide extensive numerical results for both problems for medium-size mesh networks using an iterated optimal search technique. Via numerical and simulation results, we show that (i) joint design provides a significant throughput gain over a default configuration in slotted ALOHA based wireless networks, and (ii) the throughput gain obtained by the simple network coding is significant, especially at low transmission power. We also propose simple heuristics to configure slotted ALOHA based wireless mesh networks. These heuristics are extensively evaluated via simulation and found to be very efficient.

This paper reports an outdoor experiment to optimize the timeout of wireless network coding (WNC) and frame aggregation (FA), which are implemented to carrier sense multiple access with collision avoidance (CSMA/CA)-based wireless two-hop relay prototype. The system throughput is improved. In the prototype, FA is implemented at the terminal nodes. Timeout function for WNC is available at the relay node and that for FA is available at the terminal nodes. Our outdoor experiment shows that optimizing the timeout values of WNC and FA can improve system throughput by 2.04-fold compared to the conventional relay without WNC or FA.
