Beam Index Modulation Wireless Communication With Analog Beamforming

Abstract: In this paper, we propose a new architecture and performance analysis for beam index modulation (BIM) wireless communication implemented with the aid of analog beamforming. The BIM concept is presented in order to extend and adapt the spatial modulation (SM) concept to sparse wireless communication channel environments. It is shown that when compared with the conventional beamforming and SM strategies, the BIM system can achieve higher spectrum efficiency in high signal to noise ratio (SNR) and non-line-of-sig… Show more

“…Within the context of unconventional wireless communication paradigms, there has been a growing interest in controlling the propagation environment in order to increase the QoS and/or spectral efficiency. IM-based emerging schemes such as MBM [13]- [15], spatial scattering modulation [11], and beam IM [12], use the variations in the signatures of received signals by exploiting reconfigurable antennas or scatterers to transmit additional information bits in rich scattering environments [9]. Similarly, SM schemes [4]- [6], [8], [9] create a new and extended signal constellation by exploiting the indices of the available transmit antennas of MIMO systems, still benefiting from the distinguishable propagation characteristics of different transmit antennas in rich scattering environments.…”

“…SM maps information bits onto transmit antenna indices by exploiting different fading realizations of multiple-input multiple-output (MIMO) antennas. Taking SM one step further, spatial scattering modulation [11] and beam IM [12] exploit the indices of the scatterers available in the environment to convey information. Finally, media-based modulation (MBM) utilizes reconfigurable antennas [13]- [15] by encoding the information bits onto multiple distinguishable radiation patterns [16]- [18].…”

“…This approach suffers from reduced array gain because it always uses a subarray. single-user scenario, [7] proposed beamspace-based approaches for spatial path index modulation (SPIM), which modulates the indices of the spatial paths to create different spatial patterns. The use of beamspace model is further exploited in [8] by employing lens arrays at both transmitter and receiver to improve the bit-error-rate (BER).…”

“…A joint design for analog and baseband precoders for SPIM is performed in [11] by implementing zero-forcing baseband precoding and selecting the steering vectors as analog beamformer candidates. Similar to [11], [6,7] also design the analog precoders with a predefined codebook of steering vectors, which entails a beam training task prior to the precoder design. Most of the aforementioned works investigate the single-user scenario.…”

“…This design is capable of increasing the data rate, since the information is carried by both the classic Mary alphabet and by the DM index as well as by the antenna index combination. In mmWave communications, where the channel supports a few clusters of rays, the data rate of the MS-STSK design can be further enhanced by coupling it with the concept of beam index modulation (BIM) [17]. In the BIM aided transmission, information is implicitly conveyed by the index of the beams in addition to the classic M-ary constellation.…”
