A Physical layer link channel (PLC) is a narrowband signaling channel located within the downstream OFDM channel used in data-over-service-interface specifications (DOCSIS) 3.1 system. It consists of a PLC preamble and PLC data which include informat

This paper investigates the multifarious nature of the long-term evolution (LTE) scheme and that of the modified LTE scheme for symbol timing synchronization (STS). This investigation allows us to propose a new replica correlation-based STS scheme to

So far, many studies have been made for the 802.16m sleep mode operations. However, in the previous work, the equation derivations are too complicated to be used or analytical models are not accurate. We introduce an accurate analytical model through
