GSM在无线途径上传输的一个基本概念是:传输的单位是约一百个调制比特的序列,它称为一个“突发脉冲”。脉冲继续时间优先,在无线频谱中也占一有限部分。它们在时间窗和频率窗内发送,我们称之为空地。

(A basic concept of GSM transmission over the wireless channel is that the unit of transmission is a sequence of about one hundred modulated bits, which is called a "burst". The pulse duration is prioritized and also occupies a limited portion of the wireless spectrum. They are sent within time windows and frequency windows, which we call open spaces.)
