摘要： A system and method for use of a short beacon in a wireless communication network is disclosed. In one embodiment, the method comprises generating a short beacon comprising PHY information, wherein the short beacon excludes MAC information and transmitting the short beacon via the wireless network. In general, three types of short beacons are disclosed, a first type consisting only of a PHY preamble, a second type also including a PHY header, and a third type also including a MAC header. In addition, the scheme of common beacons and individual beacons is described. Common beacons are broadcast omni-directional at the beginning of each superframe with low data rate and individual beacons are unicast to individual devices directionally with high data rate. A common beacon contains information intended for all of the devices of the network. An individual beacon contains information intended for one particular device.

摘要： A method of concatenation for LDPC encoding in an OFDM wireless system selects codewords based on the data packet payload size, wherein the payload size is the number of transmitted information bits in octets. For low transmission rates, shortening and puncturing across all codewords within the packet is applied to minimize OFDM symbol padding. For high transmission rates, only shortening across all codewords within the packet is applied to minimize OFDM symbol padding.

摘要： An improved LDPC encoding with concatenation rule and code size with packet lengths specified in octets is provided. The LDPC block size is selected to be an integer number of OFDM tones. The concatenation rule is an improvement of the shortening and puncturing scheme for low data rate. The improvement is two fold. First, the code length is selected based on the number of transmitted information bits in octets (HTLENGTH). Second, it is determined whether one extra OFDM symbol padding should be added based on the number of shortening bits in the last codeword and the available padding bits in the last OFDM symbol.
