In this paper, space-time block coding (STBC) and spatial multiplexing MIMO techniques are considered as a means of enhancing the performance of MIMO. A hyid 4x4 scheme is presented that combines spatial multiplexing and STBC to provide both increased throughput and diversity. Results showed that the proposed scheme can<b> </b>provide good</span><span lang="EN-IN" style="font-size:10.0pt;line-height:115%;&#10;font-family:&quot;Times New Roman&quot;,serif;mso-fareast-font-family:Calii;mso-fareast-theme-font:&#10;minor-latin;mso-ansi-language:EN-US;mso-fareast-language:EN-US;mso-bidi-language:&#10;AR-SA"> </span><span lang="EN-IN" style="font-size:10.0pt;line-height:115%;&#10;font-family:&quot;Times New Roman&quot;,serif;mso-fareast-font-family:Calii;mso-fareast-theme-font:&#10;minor-latin;mso-ansi-language:EN-IN;mso-fareast-language:EN-US;mso-bidi-language:&#10;AR-SA;mso-bidi-font-weight:bold">performance even under correlated channels.</span></p>
