GSM system, sends/receives radio channel data,
modulates/demodulates baseband signals on the radio

New Features
The main features of ZXG10 B8018 is shown below:
DTRU technology;
DPCT-dual power combining Transmission;
DDT-delay diversity transmission
4-way diversity reception;
IRC-Interference Rejection Combining;
intelligent power on/off;
IP Abis-interface.
New Features
New Features
The DTRU is very flexible and can be used for several
purposes . Its two TRXs, for instance, can be used
separately (the same with ever)or both,both refers to by
DPCT to improve the downlink and by four-way diversity
to improve the uplink, they can be configured to create a
super TRX.

New Features
DPCT---- Dual Power Combining Transmission:
When seeking greater cell range it is crucial to have a strong
signal from the BTS to the handset. This is often referred to
as downlink capability. This is what a handset presents as
signal strength in the display. In configurations intended for
maximum coverage, Dual Power Combining Transmission
(DPCT) feature doubles the output power from the BTS
cabinet, resulting in a significantly larger coverage area.

DDT ----Delay Diversity Transmission
Purpose: supports downlink transmitter diversity (the mobile phone
combines the best of two signals).
Implementation: by transmitting the same information on two TRXs with
a short delay and different antennas.
using only a simple software command, operators can convert the base
station from a two transceiver operational mode into the “DDT" mode,
where the two transceivers work together as one virtual transceiver, so
extending the range.
cellular downlink performance is increased by at least 3.0 decibels (dB)
at the cell border, reducing the number of sites needed by up to 30
percent over any conventional base station coverage network.

Delay Diversity Transmission
New Features
New Features
4 div RX ― 4 diversities reception
The majority of radio networks today have limited range due to
weak uplink signals from handsets. The best way to overcome
an unbalanced link budget is to ensure good receiver capability
in the base station. With the addition of a second antenna
system in the cell, we enable 4-Way Receiver Diversity
(4WRD), and this provides a total uplink that compensates for
weak handset signals.
The combination of DPCT with fully compensated uplink based
on 4-way Receiver Diversity comprises our Supreme Coverage
solution.
New Features
New Features
IRC ― Interference Rejection Combining
Another way to increase the capacity, more advanced detection
techniques have been implemented - Interference Rejection
Combining (IRC)
In maximum ratio combining (MRC) each signal is weighted with
its signal-to-noise ratio to achieve optimum performance in white
noise environments, i.e. the noise signal is uncorrelated in time.
IRC, on the other hand, takes the correlation properties of CO-
channel interferers into account to suppress them, and therefore is
able to achieve much better performance in co-channel limited
environments than MRC.
New Features
New Features
Int. Pwr on/off ― Intelligent power on/off
In order to reduce OPEX of operator, when traffic decrease
to certain value or in idle mode, this scheme automatically
to turn off part of Modules of B8018 to save power.
When traffic increase to certain busy threshold, this
scheme automatically to turn on sleep module to balance
the traffic.
The principle is as follows: CMB is able to control the switch
of all board (mainly is DTRU) in rack except interface board
(EIB/FIB) and CMB.
New Features
New Features
IP Abis
One of the primary advantages of employing IP-based
transport is the ease of maintenance arising from
convergence of core and RAN networks.
Other advantages include economic benefits and capacity
benefits
