Definitions, symbols and abbreviations Definitions For the purposes of the present document. the following terms and definitions apply. adjacent channel: A downlink adjacent channel refers to transm

43、ission in downlink direction using any one of the adjacent DSRC downlink channels at a distance of 5 MHz. i.e. in the channel at the next upper or lower centre frequency. An uplink adjacent channel refers to transmission in uplink direction using any one of the uplink communication channels related

44、to a centre frequency at a distance of 5 MHz relative to the own dounlink centre frequency. bit: acronym for “binary digit“ which can have one out of two possible values. e.g. 011 or +l/- or lowrhigh bit rate: in a bit stream. the number of bits occurring per unit time. usually expressed in bits per

45、 second bore sight: direction of maximum radiation of a directional antenna NOTE: If bore sight can not be determined unambiguously. then bore sight ma be declared by the provider. carrier frequency: frequency.fT, to which the RSU transmitter is tuned NOTE: In DSRC. the carrier frequency is in the c

46、entre of a channel. see table 2 of the present document. carrier signal or carrier: harmonic signal whose nominal single frequencq .fT, can var! within a range specified bq the carrier frequencq tolerance and which is capable of being modulated b) a second. symbol-carrying signal channel: continuous

47、 part of the radio-frequency spectrum to be used for a specified emission or transmission NOTE: A radio-frequency channel may be defined by two specified limits. or by its centre frequency and its bandwidth. or any equivalent indication. It is often designated by a sequential number. A radio-frequen

48、cy channel may be time-shared in order to allow radiocommunication in both directions by simplex operation. The term “channel“ is sometimes used to denote tuio associated radio-frequency channels. each of which is used for one of two directions of transmission. i.e. in fact a telecommunication circu

49、it. CO-channel: A downlink CO-channel refers to a transmission in downlink direction using the same frequency band of 5 MHz width. Up-link channels at the two sub-camer frequencies related to the same downlink channel (downlink centre frequency) are referred to as CO-channels. cross-polar discrimination, ellipticity of polarization: Antenna designed to transmit left hand circular waves may transmit some right hand circular waves in addition. Cross-Polar Discrimination (XPD) is defined as the ratio PLHCdPRHCP of power PLHCP of the left hand circular polarized wav
