代码描述

中文说明: SoftCast绕过了量化和前向纠错,直接对信号进行线性变化,得到具有高度抗噪能力的实数序列。然后经过简单的星座图映射得到传输的信号;由于视频信号最终的失真仅仅由信道噪声决定,因此可完全消除无线视频组播传输中的悬崖效用。


English Description:

Softcast bypasses quantization and forward error correction, and directly changes the signal linearly to get real number sequence with high anti noise ability. Then the transmitted signal is obtained by simple constellation mapping; since the final distortion of video signal is only determined by the channel noise, it can completely eliminate the interference in wireless video multicast transmission.
