Communication Signal Processing

Laboratory

1. Cloud Communication Center System
- Cloud Communication Network (CCN)
- Base station system in outdoor includes RF units only, while
all the digital units of each cell are combined together at
one place in a form like a telephone office.
- CCC System Architecture
- CCN consists of Baseband (BB) Processing Unit, RF Transceiver,

and RF-BB Network which interconnects the two units.
2. Standardization of SDR Mobile Device
- Standard Architecture and Standard Interfaces
 ⅰ. Standardization activities at WG2 of TC-RRS of ETSI (European Telecommunications Standard Institute)
 ⅱ. Portability between Software modem and Hardware platform
 ⅲ. Reconfiguration of Mobile Device with Software modem downloaded from Radio AppStore

 

3. Multiple Input Multiple Output (MIMO)
- Multi-User MIMO System for enhancing channel capacity
- Precoding and User Selection for Multi-User MIMO

4. Smart Antenna
- Smart Antenna provides a signal processing method for
enhancing the communication quality and increasing the
communication capacity by reducing the effects of interference
and noises with the nice beampattern
1. CGM
2. Lagrange
3. Power Method
