  Polar codes have been shown to approach capacity of symmetric binary erasure
channels and also have low encoding and decoding complexity. Wireless channels
are bursty in nature and a method to apply polar codes over wireless channels
is proposed. This paper investigates the performance of polar codes over
typical urban fading wireless channels. The wireless channel is modeled as a
degraded erasure channel by using an inner convolution code and interleaving.
When the convolution code fails to correct any errors, the corresponding bits
are discarded and treated as erasures. We present the performance of polar
codes over such degraded wireless channels using different code rates for the
inner convolution code.
