自动发送功率控制 - Modulation mode and transmitting power can be adaptively allocated to minimize the total transmitting power for a fixed total bits number to be transmitted and with a given qos ( ber ) being satisfied
其特点是自适应地在各子载波上选取适当的调制方式(比特数)和发送功率，保证总的发送比特数和一定的qos ( ber )要求，最小化发送功率。 - For the variable rated we studied one kind of algorithm . and transmitting power can be adaptively allocated to maximize the total transmitted bits number ( data throughput ) with the total transmitting power constraint and a given qos ( ber ) satisfied
它们的特点是自适应地在各子载波上选取适当的调制方式(比特数) ，并分配一定的功率，在满足总的发送功率约束和ber要求下最大化ofdm系统的数据吞吐量。 - Future mobile communications have to support the transmission of high rate data and multimedia applications in the radio spectrum , which is already extremely scarce . the basic idea of adaptive coded modulation is to maintain a constant throughput by varying the transmitted power level , symbol transmission rate , constellation size , coding rate or any combination of these parameters . thus , without sacrificing bit - error rate ( ber ) , these schemes provide high average spectral efficiency by transmitting at high speeds under favorable channel conditions , and reducing throughput as the channel degrades
自适应编码调制( adaptivecodedmodulation , acm )的基本思想是在不牺牲系统传输性能(比如ber )为代价的前提下,通过单独改变发送功率、波特率、编码方案、码率、调制方式,或者是综合改变前面所述的各种参数,在有利的信道条件下,获得较大的吞吐量,当信道质量下将时,相应地降低传输速率,最终达到提高平均频谱效率的目的。 - Secondly , we present a new transmit diversity scheme with adaptive power allocation in which two antennas are employed at the transmitter , and the effect of the channel estimation error on its performance is also analyzed . theoretical analysis and simulation results indicate that the new scheme has a considerable performance gain and is robust to the estimate bias of channel fading parameters
