This paper investigates the problems about the base-band signal shaping and the multi-rate signal processing of the radio-frequency signal. 本文对基带信号的成形和射频信号的多速率处理进行了研究。
Your radio transmission, furthermore, would probably be a narrow-band signal, to distinguish it from other transmissions in neighboring bands as well as naturally occurring noise. 此外,你的无线电信号可能会是一个窄带信号,以区别于邻近频带中其他的自然杂波。
