| Abstract: | The way to realize data transmission in the communication system by generating and receiving PWM from monolithic machine bears the advantages of simple in equipments preparation and lower in cost performance.Therefore,it is of great significance to study the ways to enhance the data transmission efficiency in the communication system.Based on a systematic introduction of the working principle of PWM,it proposes several ways to promote the data transmission efficiency: to employ the width of the high level and low level wave of the PWM;to optimize the key parameter of the set-up system and to adopt the Full Duplex communication system etc. |
