Real-time dual-band optical orthogonal frequency-division multiplexing (OOFDM) transceivers incorporating digital-to-analog and analog-to-digital converters operating at sampling speeds as low as 4 GS/s and field-programmable gate-array-based digital signal processing clocked at only 100 MHz are employed to explore the maximum achievable transmission performance of electro-absorption modulated laser-based...
In this paper, we proposed a novel approach to the design of MIMO transceiver for channel measurement on the system level. Transmit symbols based on the Chu sequences are adopted in the transmitter. Based on the design, a hardware platform for MIMO channel measurement in indoor environments has been developed to complete the real-time channel measurement for further channel estimation. Using the hardware...
In this paper we evaluate the real-time performance of a MIMO-enhanced 802.11a transceiver based on analog combining techniques. The aim of this transceiver design is to achieve higher performance than conventional 802.11a systems while keeping costs and power consumption similar. Also, the demonstrator used to carry out this evaluation is presented, as well as its implementation over a dual band...
