A simple but efficient video codec is built for low-bite-rate videophone applications. The goal of this project is to construct a video codec at a low cost and good performance.
In this paper, the hierarchical modulation (HM) technique is adopted in a single frequency network (SFN) to provide both global and local information.
In this paper, an equalization technique with low computational complexity is proposed for time-variant multipath channel in OFDM system.
We demonstrate through simulations and experimental measurements a low-complexity implementation of the 2x2 Golden and Silver codes in a single-carrier PDM system using the CMA equalizer.
We design a novel receiver based on the theoretical finding that the linear phase noise is uncorrelated with the nonlinear phase noise.
We consider a two-stage adaptive Vector Quantizer (VQ) that performs well on a wide variety of sources at rates of approximately 2 bits/sample.
Fixed wireless communication systems often require a subscriber antenna that is compact and low-cost, but has high antenna gain.
Fixed wireless communication systems often require a subscriber antenna that is compact and low-cost, but has a high antenna gain.
Rate adaptation technologies aim at establishing a linear relationship between power consumption and traffic load in packet networks.
We present a low-cost 0.25 μm SiGe BiCMOS technology that is being manufactured in an 8-inch production line.
