    摘要: A method for transferring data between a host device and an external device is described. The external device has FAT32 file system. The method accepts parameters for an incoming data file from the host device. Further, the method allocates memory blocks for the incoming file data on the external device based on the parameters and indexes the allocated memory blocks on a memory index table to create a file footprint. The method reads the memory index table to identify the file footprint and receives the incoming file data from the host device.

    摘要: A receiver synchronization technique is described in this disclosure that significantly reduces the convergence time for synchronization further enabling specially modulated radio frequency carrier waves using the following steps: the characteristics of the baseband signal are used to detect the start of a received burst. Once the presence of a symbol is detected, the data acquisition subsystem is enabled to begin collecting samples. These samples are then transferred to the DSP. The DSP then searches for a preamble to precisely determine the timing delay to the start of the payload data.
