In this work, we propose a mew transmission mechanisn for TCM-based cooperative communication systems when the soft-decoded-and-forward protocol is employed. In this work, we first assume that the relay node and the destination are connected by the error-free backbond. The decoding metric in this work is based on the joint probability of the received signal(More)
In an ad-hoc network, we need to find the path to the destination prior to the start of transmission between two users. In such an environment, proactive routing protocols, such as AODV and DSR, are widely used to discover a suitable routing path for two ends. However, without taking other issues, such as energy, jitter and so on, into account, the chosen(More)
Cooperative communication has been drawn much attention recently due to the benefit of diversity; however, this technique also reduces the spectral efficiency. To aim at this problem, adaptive modulation is a possible remedy to achieve better efficiency especially for the multinode cooperative communication system. In this work, the Gilbert channel model is(More)
OFDM-based communication systems have been widely used in several wireless network applications. In order to achieve a more efficient resource allocation, an novel bit and power allocation algorithm with lifetime consideration is proposed. In this work, the lifetime is specified by the portion of power or energy that a particular user can enjoy during the(More)
