Simulation and implementation of a linear predictive coder
thesis
posted on 2018-05-10, 10:31 authored by D.S.F. ChanThe main objective of this research was to design and build
a Linear Predictive Coder (LPC) based on the TMS320 processor,
and to incorporate this in the design of a low bit rate voice
coding server for a Cambridge Ring. In order to decide on a
suitable algorithm for the LPC, extensive simulations were
carried out on a BBC computer. The computer used was interfaced
to a frame store which, although its original purpose was
to store video information, acted as a suitable store for
speech. Up to six seconds of speech could be fed in from a
microphone in real time for analysis. The BBC was fitted with
a second processor, but in spite of this the processing times
were very slow. [Continues.]
