Recently, much effort has been placed toward the development of the Reconfigurable Wideband Ground Receiver (RWGR): a variable-rate, reprogrammable software-defined radio intended to supplement and augment the capabilities of the Block V Receiver. In this report, we first give an overview of the hardware architecture of the RWGR, including a detailed(More)
Recently, much effort has been placed toward the development of the Reconfigurable Wide-band Ground Receiver (RWGR): a variable-data-rate, reprogrammable receiver, whose technologies are intended for infusion into the Deep Space Network. A significant thrust of that effort has been focused on the development of field-programmable gate array (FPGA)–based(More)
In this article we characterize the effect of transmitter clock jitter upon receiver symbol synchronization performance. Using a sinusoidal model for the timing jitter, we evaluate the bit error rate (BER) degradation and cycle slip probabilities of receivers via analysis as well as simulation for uncoded offset quadrature-phase-shift-keying (OQPSK). We(More)
