Resumen:
The wavelet theory has been studied for many processing and coding applications
of signals transmitted through mobile channels. Bit-by-bit channel coding using
wavelet coefficients matrices is a technique based on the ortogonality properties
between the lines of such matrices. The principal benefits of this technique are
the simplicity of the coding and decoding process and the good performance
in fading channels. In wireless communication, multipath signal propagation
strongly degrades the quality of transmitted signals. Coding schemes combined
with diversity are used to minimize fading effects. In this work i t is presented a
technique that integrates the potentiality of the bit-by-bit coding channel using
wavelet coefficients matrices with space diversity schemes, through the use of
multiple transmitting antennas. The performance of the technique is evaluated
through simulations and comparisons with other transmission schemes.
