Co-channel interference seriously influences the throughput of a wireless mesh network. This study proposes an end-to-end channel allocation scheme (EECAS) that extends the radio-frequency-slot method to minimize co-channel interference. The EECAS first separates the transmission and reception of packets into two channels. This scheme can then classify the state of each radio-frequency-slot as ...

Wireless communication system operating over interference limited, α-k-μ multipath fading channel is considered. Closed form expressions for cumulative distribution function and level crossing rate of the ratio of two k-μ random variables and the ratio of the two α-k-μ random variables are calculated. These expressions are used for evaluation level crossing rate of wireless communication system...

We present space-time methods for channel estimation in the downlink of a UMTS/TDD system. The channels associated to all base stations near the mobile receiver are estimated by a multiuser, multi-antenna technique. We develop a minimum mean-square error (MMSE) channel estimator that incorporates midamble detection/estimation and least-squares channel estimation as preparatory stages. Combinati...

This paper proposes an interference suppression technique using nulling filter and turbo equalizer for carrier interferometry (CI) based one-cell reuse single-carrier time division multiple access (TDMA) systems. In the proposed scheme, CI technique is employed to generate CI signal which is equivalent to single carrier signal with its roll-off factor of zero. At the receiver, received CI signa...

This paper proposes and evaluates a new co-channel interference cancellation technique that utilizes orthogonal convolutional codes on a multipath Rayleigh fading channel. In a spread spectrum multiple access environment, co-channel interference (CCI) limits the performance of the communication link. To remove this interference, several CCI cancellation techniques have been proposed, including ...

Multiple-input–multiple-output (MIMO) communication systems utilize multiple transmitters to send different pieces of information in parallel. This offers a promising way communicate at high data rate over bandwidth-limited underwater acoustic channels. However, MIMO not only suffers from serious inter-symbol interference, but also critical co-channel interference (CoI), both which degrade the ...
