Parameters:
<Standard> USER | W3GPP | LTE_1M4 | LTE_3M | LTE_5M | LTE_10M |
LTE_15M | LTE_20M | WIMAX_3M5 | WIMAX_5M | WIMAX_7M |
WIMAX_8M75 | WIMAX_10M | CDMA2K | WIMAX_20M | GSM
USER
Specifies a user defined signal for transmission, define a signal
with arbitrary parameters.
W3GPP
Selects the parameters of the W-CDMA standard 3GPP FDD.
W-CDMA (
W ideband C ode D ivision M ultiple A ccess) covers the
radio technology UMTS ( U niversal M opbile T elecommunications
S ystem). 3GPP ( 3 rd G eneration P artnership P roject) is a collab-
oration between groups of telecommunication associations, which
define a globally applicable third generation mobile phone system
specification. 3GPP standardization comprises all GSM and W-
CDMA specifications.
LTE_1M4|LTE_3M|LTE_5M|LTE_10M|LTE_15M|LTE_20M
Selects an LTE ( L ong T erm E volution) signal. Based on UMTS,
LTE provides a wireless broadband internet system with voice and
other services built on top, e.g. authentication.
LTE bandwidths: 1.4 | 3.0 | 5.0 | 10.0 | 15.0 | 20.0 MHz
WIMAX_3M5|WIMAX_5M|WIMAX_7M|WIMAX_8M75|
WIMAX_10M|WIMAX_20M
Selects the digital standard IEEE 802.16 WiMAX ( W orldwide I nter-
operability for M icrowave A ccess). WiMAX provides wireless
transmission of data using a variety of transmission modes, as e.g.
point-to-multipoint links or mobile internet access.
WiMAX bandwidths: 3.5 | 5.0 | 7.0 | 8.75 | 10.0 | 20.0 MHz
CDMA2K
Selects a signal that follows the CDMA standard.
CDMA2000 ( C ode D ivision M ultiple A ccess) uses a multiple
access scheme for digital radio, to send voice, data, and signaling
data (such as a dialed telephone number) between mobile phones
and cell sites.
GSM
Selects a signal that follows te GSM/EDGE standard.
GSM/EDGE (
G lobal S ystem for M obile Communications/
E nhanced D ata R ates for G SM E volution) covers the 2nd gener-
ation mobile radio technology. Selecting this signal standard, the
sample rate is set to 270,833333 kSps. This sample rate does not
fit well into the CPRI basic frame rate. Therefore, the sampling rate
of GSM/EDGE is only achieved by using a rather complicated
group setup, the AxC settings over time.
