ETSI ETSI EN 300 175-2 V2.6.1 (2015-07) 8 1 Scope The present document is one of the parts of the specification of the Digital Enhanced Cordless T
41、elecommunications (DECT) Common Interface (CI). The present document specifies the physical channel arrangements. DECT physical channels are radio communication paths between two radio end points. A radio end point is either part of the fixed infrastructure, a privately owned Fixed Part (FP), typica
42、lly a base station, or a Portable Part (PP), typically a handset. The assignment of one or more particular physical channels to a call is the task of higher layers. The Physical Layer (PHL) interfaces with the Medium Access Control (MAC) layer, and with the Lower Layer Management Entity (LLME). On t
43、he other side of the PHL is the radio transmission medium which has to be shared extensively with other DECT users and a wide variety of other radio services. The tasks of the PHL can be grouped into five categories: a) to modulate and demodulate radio carriers with a bit stream of a defined rate to
44、 create a radio frequency channel; b) to acquire and maintain bit and slot synchronization between transmitters and receivers; c) to transmit or receive a defined number of bits at a requested time and on a particular frequency; d) to add and remove the synchronization field and the Z-field used for
45、 rear end collision detection; e) to observe the radio environment to report signal strengths. The present document includes New Generation DECT, a further development of the DECT standard introducing wideband speech, improved data services, new slot types and other technical enhancements. 2 Referen
