چکیده
In this letter, a method to construct good binary and quaternary error correcting codes, called complex Hadamard codes, based on a complex Hadamard matrix is presented. The related properties of the codes are analyzed. In addition, through the operation in Z4 domain, a new simplex soft-decision decoding algorithm for the complex Hadamard codes is also proposed. key words: complex Hadamard matrix, quaternary codes, code over rings, complex Hadamard code, decoding algorithm

Low-rate channel coding with complex-valued block codes
This paper addresses aspects of channel coding in orthogonal frequency-division multiplexing–code-division multiple access (OFDM-CDMA) uplink systems where each user occupies a bandwidth much larger than the information bit rate. This inherent bandwidth expansion allows the application of powerful low-rate codes under the constraint of low decoding costs. Three different coding strategies are c...
متن کاملComplex Valued Block Codes for Ofdm-cdma Application
This paper introduces the extension of Walsh-Hadamard block codes in order to obtain complex valued block codes. These complex valued block codes lead to an improved spectral efficiency with additional lower error rate. Applied for low rate concatenated coding schemes required for CDMA uplink transmission, the gain in spectral efficiency due to the new codes can be used for strengthening other ...
متن کاملCocyclic Butson Hadamard matrices and Codes over Zn via the Trace Map
Over the past couple of years trace maps over Galois fields and Galois rings have been used very successfully to construct cocyclic Hadamard, complex Hadamard and Butson Hadamard matrices and subsequently to generate simplex codes over Z4,Z2s and Zp and new linear codes over Zps . Here we define a new map, the trace-like map and more generally the weighted-trace map and extend these techniques ...
متن کاملNew Linear Codes over Zps via the Trace Map
The trace map has been used very successfully to generate cocyclic complex and Butson Hadamard matrices and simplex codes over Z4 and Z2s . We extend this technique to obtain new linear codes over Zps . It is worth nothing here that these codes are cocyclic but not simplex codes. Further we find that the construction method also gives Butson Hadamard matrices of order p.
متن کاملDesign of Logic Network for Generating Sequency Ordered Hadamard Matrix H
A logic network to produce the sequency ordered Hadamard matrix H based on the property of gray code and orthogonal group codes is developed. The network uses a counter to generate Rademacher function such that the output of H will be in sequency. A general purpose shift register with output logic is used to establish a sequence of period P corresponding to a given value of order m of the Hadam...
