Abstract :
Some 
noncatastrophic periodic convolutional codes with memory 
are given that have the same free distance, 
, as the best fixed code but have both a smaller number of paths of weight per time instant and a smaller average number of information bit errors per such path for periods 
, and 
. It is also shown that an 
code of period 
is equivalent to a fixed code with parameters 
.
