Welcome to the Institute of Digital Signal Processing!


MIMO, or multiple transmit and receive antennas, is an important technology to increase data throughput and link range and to combat against channel fading in wireless communications. It has become a de-facto standard in modern wireless communication systems such as IEEE 802.11n (Wi-Fi), 3GPP LTE, WiMAX and HSPA+. DSV scientists have studied MIMO-related problems for more than a decade, covering the areas of beamforming, space-time coding, channel capacity, equalization, interference alignment, signal estimation and detection, etc. Beside the above mentioned mass market MIMO-based wireless communication standards, DSV has also expertise in applying MIMO-related technology to industrial niches: as a successful example, we have applied advanced blind signal processing technique to a multi-sensor pulse telemetry problem, where the signal to be estimated is immersed in extremely strong disturbances with the involved channel being time-varying and unknown. In the future, DSV will focus on combing MIMO principles with extreme bandwidth wireless systems, RFID systems, and cellular cognitive radios.
