Capacity Maximization and Error Rate Performance of OFDM using MIMO in Software Defined Radio
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 3
Abstract
Orthogonal Frequency Division Multiplexing (OFDM) is one of the modulation techniques in Software Defined Radio. Peak to Average Power Ratio (PAPR) and Secondary Power Ratio (SPR) is taken into consideration to increase the Signal to Noise Ratio (SNR) in OFDM and to lessen the PAPR on the receiver side, Multiple All Pass filter is used along with the clipping technique. FEC coding is performed by suggesting convolution order. Bit Error Rate (BER) performance is analysed by varying window size, bits per symbol and modulation schemes. In the recent years, Multiple Input and Multiple Output (MIMO) is a captivating technology for wireless system. In order to transmit maximum number of information without delay and collision, the capacity of the MIMO channel is increased with the help of modified water filling algorithm. Inter Carrier Interference (ICI) and Inter Symbol Interference (ISI) are overcome with the help of the group pilot algorithm.
