【Abstract】 In laser communication, the output signal of photoelectric conversion is very weak. In order to collect and process the weak signal accurately with high speed and to improve the sensitivity of the receiver, a DSP system adopting over-sampling based on TMS320F2812 was advanced. It analyzed and proposed several efficient ways to eliminate system error through experiments. The result presented the excellent performance of the system.更多还原
