A novel generalized optimization criterion for transmit signal design in Joint Transmission (JT) multiuser downlinks
نویسندگان
چکیده
Joint Transmission (JT), a novel downlink transmission scheme, was introduced and described in recent papers. The crux of JT consists in exploiting channel state knowledge at the base stations to jointly generate a common transmit signal for the support of all mobile terminals, with the aim to directly eliminate intersymbol interference and intracell multiple access interference while transmitting. The transmit signal design process offers further degrees of freedom for transmit signal optimization, which have only been insufficiently exploited yet. In this paper a generalized more sophisticated approach to transmit signal optimization is presented and demonstrated how to adapt the JT transmit signal design process correspondingly. A discussion of application aspects and exemplary numerical results completes the paper.

Spread Spectrum CDMA systems suffer from interference in frequency-selective channels. For the uplink, Multiuser Detection (MUD) mitigates the interference. For the downlink, Multiuser Transmission (MUT) is possible, provided that an estimation of the channel impulse response is available. A novel MUT approach is proposed, which outperforms other MUT methods, like Joint Transmission (JT) and di...

متن کاملA Hybrid Approach to Spatial Multiplexing in Multiuser MIMO Downlinks
In the downlink of a multiuser multiple-input multiple-output (MIMO) communication system, simultaneous transmission to several users requires joint optimization of the transmitted signals. Allowing all users to have multiple antennas adds an additional degree of complexity to the problem. In this paper, we examine the case where a single base station transmits tomultiple users using linear pro...

In ultra-dense networks (UDNs), distributed radio access points (RAPs) are configured into small virtual cells around mobile users for fair and high-throughput services. In this correspondence, we evaluate the performance of user-centric joint transmission (JT) in a UDN with a number of virtual cells. In contrast to existing cooperation schemes, which assume constant RAP transmit power, we cons...

In this paper, we propose a multiple-input multipleoutput (MIMO) beamforming scheme for a multiuser system in frequencyselective fading channels. The maximum signal-to-noise and interference ratio (MSINR) is adopted as a criterion to determine the transmit and receive weight vectors. In order to maximize the output SINR over all users, two algorithms for base station are considered: the first a...
