SPACE TIME BLOCK CODING WITH PILOT PATTERN FOR PERFORMANCE ENHANCEMENT BASED ON MIMO-OFDM IN HET-NET SYSTEM

In multiple input multiple output orthogonal frequency division multiplexing (MIMO-OFDM) frameworks, the channel state data ought to be known by the beneficiary for acquiring transmitted information. Channel estimation algorithms are utilized to look at the multipath effects of frequency selective Rayleigh blurring channels. It acquires the required channel data ahead of time with the aim of making the piloting code of the transmitter progressively proficient to influence the receiver to detect signals more effectively. MIMO-OFDM is an attractive technique for next-generation wireless systems. However, the performance of wireless links is severely degraded due to various channel impairments which cause a decoding failure and lead to packet loss at the receiver. One technique to cope with this problem is the space-time block code (STBC). This paper presents experimental results on the performance of a MIMO-OFDM system with STBC as measured in MATLAB software. The average bit error rate (BER) performance and higher SNR optimization is a key contribution of this research paper. It has been shown that STBC can be implemented in real-world scenarios and guarantee the reliability of loss-prone wireless channels
