Document from the year 2014 in the subject Communications - Multimedia, Internet, New Technologies, grade: B, , course: Advanced Wireless Communication System, language: English, abstract: This report investigates antenna-grouping algorithms, which are hybrids of beamforming and spatial multiplexing. With antenna grouping, we can achieve diversity gain through beamforming and spectral efficiency through spatial multiplexing. We will review existing criteria and present several new criteria in multiple-input-multiple-output (MIMO) antennagrouping systems where the number of transmit antennas is…mehr

Document from the year 2014 in the subject Communications - Multimedia, Internet, New Technologies, grade: B, , course: Advanced Wireless Communication System, language: English, abstract: This report investigates antenna-grouping algorithms, which are hybrids of beamforming and spatial multiplexing. With antenna grouping, we can achieve diversity gain through beamforming and spectral efficiency through spatial multiplexing. We will review existing criteria and present several new criteria in multiple-input-multiple-output (MIMO) antennagrouping systems where the number of transmit antennas is larger than that of receive antennas. Novel low complexity antenna grouping algorithm is also proposed whose BER and computational complexity will be compared with existing criteria. The BER of lower bound of the proposed algorithm will also be derived in independent and identically distributed channels by using the probability density function of the largest eigenvalue of a Wishart matrix.
