Simulation of SC-FDMA System with Space Time Block Coding (STBC)

چکیده
Throughout wireless communication systems, Orthogonal Frequency Division Multiplexing (OFDM) and also Single-Carrier Frequency Division Multiple Access(SC-FDMA) contributes a significant part. It has been adopted by a variety of future mobile communication standards like WiMAX, Long-term Evolution (LTE), LTEAdvanced and also Ultra Mobile Broadband (UMB) and many others. SC-FDMA can be interpreted as a linearly precoded OFDM scheme in the sense that it has an additional DFT processing step preceding the standard OFDM processing.SC-FDMA is a technique which utilizes single carrier modulation at the transmitter and frequency domain equalization at the receiver and has almost similar performance and essentially the same overall structure as those of an OFDM system.Its one most important benefit over OFDM is that it has lower peak-to-average-power-ratio(PAPR).It is an attractive substitute to OFDM, especially in the uplink communications where lower PAPR greatly benefits the mobile terminal in terms of transmit power efficiency. SC-FDMA is currently a working theory for the uplink multiple access scheme in 3GPP Long Term Evolution (LTE).This work presents the simulation of SC-FDMA in GUI MATLAB.In this,we have used an application of Space Time Block Coding(STBC) for SC-FDMA in order to combat severe effects of fading.

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

Due to various shortcomings of OFDM, like it is sensitive to Doppler shift, frequency synchronization problems, loss of efficiency caused by cyclic guard interval, it was endorsed to use coding algorithms like STBC which improves efficiency. Another way of increasing the efficiency is using a multiple – access technique like SC-FDMA. SC-FDMA can be described as linearly Pre-Coded OFDMA scheme, ...
متن کاملFrequency-Domain Equalization for Single-Carrier Space-Time Block Coded Transmit Diversity in a High Mobility Environment
Single-carrier (SC) transmission with space-time block coded (STBC) transmit diversity can achieve good bit error rate (BER) performance. However, in a high mobility environment, the STBC codeword orthogonality is distorted and as consequence, the BER performance is degraded by the interference caused by the orthogonality distortion of STBC codeword. In this paper, we proposed a novel frequency...
