Abstract:Link Adaptation Technology adjusts transmit power and modulation schemes, etc, according to wireless channels, so as to make the best use of the wireless channel resources. In order to fulfill the 3G demands for various data rates and flexible QoS, this paper proposes a bit and power allocation algorithm based on antenna selection, which combines the advantages of antenna selection, bit allocation and power allocation. This algorithm aims at maximizing the data transmission rate in confined BER. The simulation results show that this algorithm can effectively increase the data transmit rate compared with the original algorithm.
Keywords:antenna selection  power allocation  adaptive modulation
