The CRLBs are investigated for both single pulse sysKeywords: Codes (standards); Error analysis; Multipath propagation; Parameter estimation; Pulse modulation; Spread spectrum communication; Synchronization; Code tracking; Time delay; Time hopping; Ultra-wideband signals; Wireless telecommunication systems20042015-12-08
