Patent ID: 6947500

Claim:
A satellite data reception system comprising: a channelizer which receives a frequency spectrum containing samples of a band transmitted from a transmitter over a wireless link and divides the frequency spectrum into subbands including a sequence of the data samples comprising a time division multiplexed signal from multiple channels output by the channelizer with each successive data sample belonging to a channel different from a channel to which an immediately preceding data sample belongs; a multiple channel phase tracking coupled to the time division multiplexed signal from the multiple channels which outputs sequentially groups of most likely bits and from hard decisions from multiple channels; a first memory, coupled to groups of most likely bits, which stores the groups of most likely bits from the multiple channels and outputs a sequence of data groups equal to a number of the multiple channels with each data group containing a plurality of samples from one of the multiple channels; an inner decoder, responsive to the sequence of data groups from the first memory, which outputs decoded data groups from the multiple channels; a second memory, coupled to the decoded data groups from the multiple channels and to the hard decisions from multiple channels, which stores the decoded data groups and the hard decisions into data blocks which are sequentially output by the second memory; and an outer decoder which decodes the sequentially output data blocks from the second memory.
