“…Otherwise in our system we can obtain BER of 10 -4 for EbN0 of 5dB. In other contribution [6] they can obtain 9 dB improvement at 2*10 -4 BER with LDPC concatenated with STBC. Figure 11 shows the performance of BCH-TURBO system with and without interleaver, the BCH-TURBO with block interleaver and matrix interleaver provide just 1 dB at 10 -6 at the cost of introducing additional time-delay, memory space requirements, and system complexity.…”

“…In [5] different schemes of concatenated STBC and channel coding as TCM (trellis codes modulation), CC (Convolutional Code), turbo, turbo BCH and Turbo TCM was been analyzed and it showed that TC (turbo Indonesian J Elec Eng & Co mp Sci ISSN: 2502-4752  codes) gave the best coding gain with a moderate complexity. In [6] concatenation of STBC and LDPC (low density parity check) was studied and it was shown that this concatenation provide a coding gain of 9 dB at 10 -4 as compared with uncoded STBC and in [7] new concatenated scheme was developed to perform better performance. As well as in [8], where a novel hybrid space time blocks coding scheme was studied and compared with an uncoded STBC and it proves better performance.…”

Recently, OSTBCs has become a widespread technique for signal transmission over wireless channels because of their diversity gain, but there are not designed to achieve an additional coding gain. Hence, OSTBCs must be concatenated with an external code which allows a significant coding gain.FEC (forward error correction) is a technique used for detecting and possibly correcting errors that can occur when messages are transmitted through a digital communication system, also for rendering the information more reliable. Thus, with staffing these coding techniques that are able to reach Shannon limits, in MIMO systems, better performances can be achieved by taking advantages of diversity and coding gains. The objective of this paper is to compare different FEC codes in Rayleigh fading channel and propose an appropriate code for MIMO-OSTBC systems. The simulation results reveal the performance of the proposed model

“…Therefore for the proposed system, TURBO codes are used as inner code for the concatenation with for SINR of 8 dB whereas the same is achieved for more than 14 dB for TAS-OSTBC-TURBO case as shown in Fig.3. The proposed TAS-OSTBC system concatenated with BCH-TURBO is compared with TAS-OSTBC system concatenated with TURBO code and TAS-OSTBC system concatenated with LDPC code as given in [7]. It is observed from Fig.…”

Transmit Antenna Selection (TAS) technique with Orthogonal Space Time Block Code (OSTBC) addresses the problem of hardware complexity in multiple antenna systems and improves Bit Error Rate (BER) significantly by using various antenna selection algorithms. TAS technique is not able to provide the coding gain. To achieve the coding gain benefits with improvement in BER, it is necessary to concatenate TAS system with an outer code. In literature, it is observed that the concatenation of Forward Error Correction (FEC) codes and Space Time Block Code (STBC) for MIMO systems provides the high coding gain with improved BER. In this paper, a multiple TAS-OSTBC system is proposed with concatenation of channel coding techniques such as BCH and TURBO. The proposed system is concatenated with BCH as outer code in series with TURBO as inner code. This combination provides the capacity benefits of TAS-OSTBC system with improved coding gain. The channel is assumed to be faded by Nakagami- m fading. It is observed that for multiple TAS-OSTBC system this new concatenation of BCH-TURBO code gives improvement of 5 dB at 10-6 as compared to concatenation of TURBO code at m =0.5 for Nakagami- m fading parameter.
