FREQUENCY OFFSET DIFFERENTIAL PULSE POSITION MODULATION

摘要

A frequency offset differential pulse position modulation scheme is used to transmit data between computing devices (105A, 105B) within a wireless network system (100). The differential pulse position modulation component of the scheme provides relative immunity to interference for the system (100) by utilizing a blanking time between pulse positions, which is large enough to allow the interference between frequency offset-differential pulse position modulation pulses to subside. The frequency offset component of the scheme enables the system (100) to utilize multiple frequency channels to achieve higher data rate. Utilizing a time offset between the frequency channels reduces the blanking time, thereby increasing the amount of data that can be transmitted with a set period of time.
