In this paper Orthogonal Frequency Division Multiplexing (OFDM) has been implemented on Multipath Rayleigh Fading Channel and AWGN channel models. An in depth comparison of BER enhancement using Viterbi Decoder, Frequency and Time Interleaving has been executed. It has been demonstrated through the simulation result how the use of the Viterbi decoder in conjunction with both time and frequency interleaving...
In this paper a single stage power amplifier is designed at 1 GHz frequency. This amplifier provides high output Gain using optimized input and Output matching circuits using lumped components. The amplifier is used along with a VCO in order to increase the total output gain needed for the antenna measurement system. This Power amplifier is provided with a Vcc Supply of 5 Volts. Input and output circuits...
