定义了环Z4上长度为n的线性码的广义Lee重量计数器,给出了环Z4上长度为n的线性码的广义Lee重量的Mac Williams恒等式.进一步,使用Krawtchouk多项式,获得了环Z4上长度为n的线性码的等价形式的广义Lee重量的Mac Williams恒等式.
The generalized Lee weight enumerators for linear codes of length n over Z_4 were defined and the generalized Lee weight MacWilliams identities for linear codes of length n over Z_4 were given.Furthermore,by means of Krawtchouk polynomials,the equivalent form of the generalized Lee weight MacWilliams identities for linear codes of length n over Z_4 was obtained.
