The paper expounds the expressing format of SNMP PDU and the rule of BER encoding, gives an example of the coding of GetRequest PDU, and advances one effective way of searching the SNMP agent: first utilize the rule of BER coding to encode the GetRequest PDU to be transmitted in the SNMP management station with reference to the format of SNMP PDU, then encapsulate it into UDP packet and transmit it...
Timing synchronization is a preeminent challenge in ultra-wideband impulse radios (UWB-IRS). The conventional all-digital synchronization methods encounter some formidable implementation difficulties such as high rate sampling and high complexity RAKE structure. To avoid these challenges, semi-analog methods have been motivated recently. We propose a code-assisted blind synchronization (CABS) algorithm...
Pseudo Chaotic Time Hoping (PCTH) is a recently proposed modulation scheme for UWB impulse radio. Unlike a typical TH-UWB, the PCTH-UWB system exploits concepts from symbolic dynamics to generate aperiodic sequences which modulate the position of pulses. The use of aperiodic TH sequence can enhance the spread-spectrum characteristics of UWB system by removing the spectral feature of the transmitted...
