rms Angular Spread Estimation using CDM based MIMO Channel Sounder with Loosely Synchrounous Codes and Kasami Codes
This paper presents rms angular spread estimation using the code-division multiplexing (CDM) based MIMO channel sounder applied loosely synchronous (LS) codes and Kasami codes for real time measurement of MIMO radio channel. Since this scheme has drawback of reduced dynamic range depending on the number of transmit antennas, it is important that low correlation codes should be utilized to get reliable performance. In this paper, the proposed scheme adopts two efficient codes, LS codes and Kasami codes, of which performance is investigated through Monte-Carlo simulation in 2×8 and 4×8 MIMO channel environment, respectively. According to the simulation focused on rms angular spread estimation, LS codes can be used for 2×8 MIMO channel measurement and Kasami codes is suitable for measuring 4×8 MIMO channel. For measuring 4×8 MIMO channel with LS codes properly, some modification is taken to the LS codes. Unitary ESPRIT is chosen for DOA estimation and rms angular spread is taken for the performance comparison.
