Functions
The ZXMBW E9230 provides the following functions.
Forward Signal
Processing
� Performs OFDMA modulation, MAC layer processing, digi-
tal up-conversion, intermediate frequency amplification, RF
power amplification and transmit filtering on received base-
band signals and then transmits them by using the antenna.
� Implements MAC layer scheduling and power control.
� Detects baseband signal power and antenna interface power in
FPGA of the digital domain.
� Accomplishes wave standing ratio detection on the forward an-
tenna interface.
� Implements forward automatic calibration and manual calibra-
tion.
Reverse Signal
Processing
� Receives reverse RF WiMAX signals from space and performs
band pass filtering, low noise amplification, RF RF mixing and
digital down-conversion on these signals and then sends them
to the baseband OFDMA modulation and MAC layer processing.
Afterwards, the baseband sends these signals to AGW through
the R6 interface for interconnection with the core network.
� Supports reverse RSSI and reverse spectrum scan functions.
� Accomplishes reverse automatic gain control.
Clock Processing � Implements GPS clock signal abstraction and clock recovery.
� Supports clock cascading.
� Accomplishes clock signal distribution.
Other Functions � Monitors and manages WDPA signals.
� Monitors and manages the power supply.
� Monitors and manages the electrically tuned antenna.
� Monitors external equipments through dry contacts and RS485
interface.
� Implements TDD time sequence regeneration.
� Accomplishes version monitoring and version management.
