Comparative study of turbo equalization schemes using convolutional, convolutional turbo, and block-turbo codes [PDF]
Turbo equalizers have been shown to be successful in mitigating the effects of inter-symbol interference introduced by partial response modems and by dispersive channels for code rates of R/spl les/ 1/2. We comparatively studied the performance of a range of binary phase-shift keying turbo equalizers employing block-turbo codes, namely Bose-Chaudhuri ...

New High Performance Deterministic Interleavers for Turbo Codes
Turbo codes offer extraordinary performance, especially at low signal to noise ratios, due to a low multiplicity of low weight code words. The interleaver design is critical in order to realize an apparent randomness of the code, thus further enhancing

System Performance of Concatenated STBC and Block Turbo Codes in Dispersive Fading Channels
A new scheme of concatenating the block turbo code (BTC) with the space-time block code (STBC) for an OFDM system in dispersive fading channels is investigated in this paper.

Turbo Codes Performance Optimization over Block Fading Channels
In this paper, the best achievable performance of a turbo coded system on a block fading channel is obtained, assuming binary antipodal modulation. A rate 1/3 turbo code is considered, obtained by concatenating, through a random interleaver, an 8-states rate 1/2 and a rate 1 convolutional codes (CC).

Concatenated space-time block codes and TCM, turbo TCM, convolutional as well as turbo codes [PDF]
Space-time block codes provide substantial diversity advantages for multiple transmit antenna systems at a low decoding complexity. We concatenate space-time codes with convolutional codes (CC), turbo convolutional codes (TC), turbo BCH codes (TBCH), trellis coded modulation (TCM) and turbo trellis coded modulation (TTCM) schemes for achieving a high ...

DIFFERENT FPGA PRODUCTS BASED IMPLEMENTATION OF LTE TURBO CODE
In the long-term evolution (LTE) physical layer, using turbo code is considered as the paramount one in error-correcting coding. This paper presents an implementation of LTE turbo decoding using the Log- Maximum a posteriori (MAP) algorithm with reduced ...
