Orthogonal Frequency Division Multiplexing (OFDM) is an emerging field of research in the field of wireless communication and finds its application where high data rate is required at low latency and better spectral efficiency. Peak to Average Power Ratio (PAPR) is the limiting factor for an OFDM system as it degrades the system performance by reducing SQNR(More)
– In this paper two linear channel estimation techniques, Least Square Error (LSE) and Linear Minimum Mean Square Error (LMMSE) along with their modified versions, for reduced complexity, are discussed for LTE-Advanced which is based on MIMO-OFDM technology. LMMSE demonstrates better performance but with more complexity than LSE because it requires channel(More)
Optimization of the communication systems is one of the big challenges to the modern world. The problem is nicely dealt by the GNU Radio; a cheaper and powerful tool. GNU Radio companion (GRC) gives the simplicity to use as is the case with normal Python language used for programming. The Universal Software Radio Peripheral (USRP) gives the boost to GNU(More)
Development in the wireless communication systems is the evolving field of research in today's world. The demand of high data rate, low latency at the minimum cost by the user requires many changes in the hardware organization. The use of digital modulation techniques like OFDM assures the reliability of communication in addition to providing flexibility(More)
