    • A system (1300), method, and apparatus (1900) are provided for a source to choose a partner / relay from at least one candidate(1302) (1303) to transmit at least part of a message from the source (1301) to destination (1304). The choice depends on the channel conditions of the source (1301) and when the source is experiencing poor channel quality to the destination, the source selects the candidate and the modulation modes of the source (1301) and partner / relay (1302) (1303) such that the frame error rate (FER) of the source(1301) is lowered. Otherwise, a modulation mode is selected for each of the source (1301) and the partner / relay (1302) (1303) that most improves the gain in throughput of the source (1301). The present invention applies to modes consisting of binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), and 16 -state quadrature amplitude modulation (16- QAM).
    • 提供了一种系统(1300),方法和装置(1900),用于源从至少一个候选(1302)(1303)选择对方/中继,以将消息的至少一部分从源(1301)发送到 目的地(1304)。 选择取决于源(1301)的信道条件,并且当源正在经历到目的地的差的信道质量时,源选择源(1301)和伙伴/中继(1302)(1303)的候选和调制模式 ),使得源(1301)的帧错误率(FER)降低。 否则,为源(1301)和对象/中继(1302)(1303)中的每一个选择最大程度地改善源的吞吐量增益的调制模式(1301)。 本发明适用于由二进制相移键控(BPSK),正交相移键控(QPSK)和16态正交幅度调制(16-QAM)组成的模式。
