Performance Analysis of Hybrid beam M-MIMO for High Frequency Range

Resumen

With the Advanced development in the field of wireless communication (From 4G to 5G&6 G), there is a noticeable increase in the number of devices, that is going to rise exponentially. Any two users communicating with each other using different communication bands is the major requirement associated with mm-wave communication, or in other ways for 5G and 6G (Next Generation), the requirement for filling this generation gap between different mobile generations is a major challenge in the market. It is vital important whatever frequency band is used, that frequency band provide spectrum efficiency and also used efficiently to serve the maximum number of users, besides this all intra-band communication is also the challenge in the case of the next generation after 4G. The role of spectrum sensing and spectrum changing play a major area of research for new-generation technology. Hybrid precoding for Massive- MIMO is a very popular algorithm used for 5G. This is a very useful technique for improving the data rate. The received signal quality is also another important parameter, Error Vector Magnitude is a very popular figure of merit used for determining the quality of the signal received, this vector gives the difference between the expected and the actual received signal value. This parameter is used in this paper for judging the performance of different higher frequencies. The Massive-MIMO techniques is well known to perform strongly in the 5G frequency band.

This paper works towards the performance of 6G(mm waves) in terms of Error Vector Magnitude(EVM) and Bit Error Rate (BER). The Hybrid precoding for Massive MIMO uses many antennas for beam forming. This structure is very complex and costly, so the range is also playing a significant role in this communication band. In this research, the hybrid precoding model versatility for 6G is tested, the considerable frequency bands for testing are 50GHz, 70GHz, 100GHz, and 120 GHz.
