We introduce a novel broadcast network architecture, where macro and micro base stations (BS) transmit partially the same signal in a SFN manner. Leveraging this architecture we propose to operate the medium as a pure IP multicast bearer coupled with a feedback channel for scheduling and optimizing the bandwidth usage. The extra bandwidth can be managed locally with a fine grain thanks to the dense...
Classical ML decoders for multiple input multiple output (MIMO) systems like the sphere decoder, the Schnorr-Euchner algorithm, the Fano and the stack decoders suffer from high complexity for high number of antennas and large constellation sizes. In this paper, we propose the use of parallel processing for stack decoding, to decode signals transmitted on linear MIMO channels to reduce time consumption...
In this paper, we investigate the use of soft output decoders for signals transmitted on linear channels when applied to multiple input multiple output (MIMO) systems. A new soft output MIMO decoder is proposed. It's an extension of the hard stack decoder. A straightforward idea was to exploit internal nodes still stored in the stack at the end of hard decoding process to calculate LLR. We show that...
A very high time domain resolution channel sounder dedicated to the 60 GHz band indoor channel is presented. Based on Cox technique, it provides a 3 ns delay resolution. The value of the sliding factor k and the analysed impulse response length are electronically programmable, which allows a maximum Doppler analysis of more than 25 kHz. In all cases, the sampling frequency is minimised and direct...
