In this paper, a new model and compensation scheme of quadrature imbalance in analog I/Q OFDM transceivers is presented. Classically, the effect of I/Q imbalance is modeled by a cross-talk between pairs of symmetrical OFDM sub-carriers. We show that this model is not valid when the carrier frequency offset is compensated after the source of I/Q mismatch.(More)
A massively parallel machine based on Serial RapidIO (SRIO) interconnect is presented in this paper. The proposed machine consists of multi digital signal processors (multi-DSPs) and multi-cores in one DSP. A core is the basic processing element and the SRIO is the inter-processors communication bus. This paper presents several cases studies of traffic(More)
Machine vision algorithms require high-computing power. A high performance parallel system has been proposed in this paper by implementing a road traffic radar video processing chain in real-time on a new embedded architecture. The proposed machine consists of the Digital Signal Processor (DSP) 66AK2H12 from Texas Instruments (TI). The goal of this paper is(More)
