Channel Decoder Design of Physical Broadcast Channel for Coverage Enhancement in LTE

Recently, Long Term Evolution (LTE) are proposed for machine type communication (MTC) of the low-cost devices in 3GPP discussion. However, some MTC devices may be located in poor environment with high penetration loss such that some enhancements are required to ensure the radio coverage.Physical broadcast channel (PBCH) carries the most important system information for the devices to access the network. In this paper, we propose a new PBCH decoder with lower the decoding complexity to improve the coverage for PBCH. Following the 3GPP simulation settings, we observe performance gain so that we believe the proposed low-complexity channel decoder design is promising for the coverage enhancement in LTE.
