whitepaper This paper introduces a linear constellation precoded OFDM for wireless transmissions over frequency-selective fading channels. Orthogonal frequency-division multiplexing (OFDM) converts a frequency-selective fading channel into parallel flat...

whitepaper This paper identifies the maximum achievable diversity order for i.i.d.or correlated Rayleigh fading channels and also provide design rules for achieving maximum diversity gains with LP-OFDM. Orthogonal Frequency Division Multiplexing (OFDM...

whitepaper This adaptation is done by varying the number of substreams and the rate of each substream in a precoded spatial multiplexing system. Multiple-Input Multiple-Output (MIMO) wireless systems obtain large diversity and capacity gains by employing...

whitepaper In this paper, OFDM is considered as an implementation of linearly precoded MIMO spatial multiplexing systems over frequency selective channels. The knowledge of the wireless channel is crucial for realizing the capacity and diversity gains of a...
