换句话说,信号可能仍然是

探测到,但以较低的质量。这是通常所说

对软失败。幸运的是,新的传输的多样性

方案提供了相同软失败。对-one of the receive chains fail, and the other receive

chain is operational, then the performance loss is on the order

of the diversity gain. In other words, the signal may still be

detected, but with inferior quality. This is commonly referred

to as soft failure. Fortunately, the new transmit diversity

scheme provides the same soft failure. To
