Multiple-input multiple-output spatial multiplexing (MIMO-SM) ultrawideband (UWB) systems with orthogonal frequency division multiplexing (OFDM) signaling are developed. It is shown that the proposed linear and nonlinear receivers offer substantial spatial diversity beside data rate enhancement.

In this paper, we study the reliability (error probability) and rate tradeoffs among the receivers in single-antenna block Rayleigh-fading Gaussian broadcast channels. The rate and reliability tradeoffs are quantified through the notions of average multiplexing and diversity gains in the high signal to noise ratio (SNR) regime. Diversity and multiplexing gains that can be simultaneously achieve...

Generalized frequency division multiplexing (GFDM) is considered a non-orthogonal waveform and known to encounter difficulties when using in the spatial multiplexing mode of multiple-input-multiple-output (MIMO) scenario. In this paper, a class of GFDM prototype filters, under which the GFDM system is free from inter-subcarrier interference, is investigated, enabling frequency-domain decoupling...

In LTE /LTE -advanced standards, the physical layer is mapped into multiple transmission modes(TM) and each TM should be dynamically selected depending on the time-varying MIMO channel. Besides the single antenna SISO transmission (TM1), multielement antenna (MIMO) technology such as Open Loop Spatial Multiplexing (OLSM) and Close Loop Spatial Multiplexing (CLSM) transmission are also specified...

A primary design decision in HTTP/2, the successor of HTTP/1.1, is object multiplexing. While multiplexing improves web performance in many scenarios, it still has several drawbacks due to complex cross-layer interactions. In this paper, we propose a novel multiplexing architecture called TM that overcomes many of these limitations. TM strategically leverages multiple concurrent multiplexing pi...
