bell transmitter

基本解释

During one of the first public demonstrations of the “Bell Solar Battery” the device powered a small radio transmitter, carrying both speech and music.
最初的公开示范之一便是将一台小型无线电发射器装上“贝尔太阳能电池”，传送讲话与音乐。
Then, after a 12-day gap in 1876—when Bell went to Washington to sort out patent questions about his work—he suddenly began trying another kind of voice transmitter.
之后在1876年，经过了12天的瓶颈后--当贝尔去华盛顿处理关于他工作上专利的问题时--他突然开始尝试另一种声音的传送器。
At the transmitter, vertical-bell laboratory layered space-time (VBLAST) is suitable for multiple modulation and coding scheme (MCS) on different antennas, which can also enhance channel capacity.
首先在接收机采用了VBLAST编码，使得每根天线上可以选择不同调制编码方式（MCS），这样可以有效地提高信道容量。

And the transmitter design that Bell immediately sketched in his notebook upon his return to Boston was identical to the sketch of the transmitter that Gray had submitted to the Patent Office.
