MIMO OFDM ( Multiple Input Multiple Output)

ofdm is the important technology for future wireless communication. battery power is constraint one. to improve this many energy efficiency scheduling are used along with power allocation technique

OFDM and how to generate the signal and scheduling methode with CQI

The 4g wireless uses Orthogonal Frequency Division Multiplexing (OFDM), Ultra Wide Radio Band (UWB), and Millimeter wireless. Data rate of 20mbps is employed. Mobile speed will be up to 200km/hr. The high performance is achieved by the use of long te
