The OR channel provides an unusual opportunity where single-user decoding permits operation at about 70% of the full multiple-access channel sum capacity. The interleaverdivision multiple access technique applied in this paper can approach that performance with turbo and LDPC solutions. The current paper focuses on very low latency codes with simple Viterbi decoding, intended for very high spee...

This paper presents the capacity performance of multiple antennas for wireless communication systems. Multiple antennas structures can be classified into single-input multiple-outputs (SIMO), multiple-inputs single output (MISO), and multiple-inputs multiple-outputs (MIMO) systems. Assuming that the channel is unknown at receiver, capacity expressions are provided for each structure. Our result...

This paper considers the transmission of multiple descriptions over noisy channels rather than the on-oo channels that are traditionally considered. We introduce the use of iterative decoding techniques similar to those used in \turbo" decoding to decode multiple correlated descriptions transmitted over a noisy channel. For a given transmission rate per channel and a given channel state, the ee...

Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems play a vital role in the channel estimation. The wireless channel suffers from impairments like fading and interference. Technologies that achieved above requirements are Multiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM). Channel impairments must be mitigated a...

This study tests the assumption that the characteristics of channels within multiple channel rivers are different from those of single channel rivers. Some river restoration approaches propose radical transformation of river patterns, from multiple to single channels, based on the link between river patterns and their in-channel characteristics. Determining the links between river patterns and ...

After Typhoon Morakot, dredging engineering was conducted while taking the safety of humans and structures into consideration, but partial stream reaches were formed in the multiple-channel sections in Cishan Stream because of anthropogenic and natural influences. This study mainly explores the distribution of each fish species in both the multipleand single-channel sections in the Cishan Strea...

In order to enhance the transmission rate, multiple channels and multiple transceivers are employed in wireless mesh networks (WMNs). However, the bandwidth utilization rate is still low, and it is hard to design efficiency MAC. There are mainly three reasons. The first reason is that there are different kinds of nodes in WMN: some nodes are single transceiver and some nodes are multiple transc...

In this paper, we derive a capacity region for Gaussian fading multiple access degraded relay channel with partial channel state information (CSI) at the transmitters (CSIT) and perfect CSI at the receiver (CSIR). The achievable rate region obtained by Kramer-Wijngaarden is a special case of our region. Keywords-Gaussian fading channel; channel state information (CSI); discrete multiple access ...

Because of broadband wireless systems benefit from accurate channel characterization, there is growing interest in broadband wireless multiple-input multiple-output (MIMO) channel models. While coding and signal processing are key elements to successful implementation of a MIMO system, the communication channel representing a major component that determines system performance. This paper will f...

In this paper, we present a routing and channel assignment protocol for multi-channel multi-hop wireless networks. We view a multi-hop network as an extension to infrastructure networks, where a mobile host may connect to an access point using multi-hop wireless routes, via other mobile hosts or wireless routers. The access points are configured to operate on one of multiple available channels....
