Patent ID: 8630364

Claim:
A method comprising: placing a multi-modulation index continuous phase encoder (CPE) in a known initial state prior to receiving a data block; receiving, at the CPE, a data block that includes one or more symbols; determining one or more termination symbols to be appended to the received data block, including: determining, after the data symbols have been received by the CPE, a partial cumulative phase associated with each of a plurality of modulation indexes for the CPE; determining one or more partial termination symbols having a non-zero value for each modulation index; determining one or more partial termination symbols having a zero value for one or more of the modulation indexes, wherein the partial termination symbols are determined to force the partial cumulative phase associated with each of the modulation indexes to zero after the CPE has received the data block and the termination symbols; and mapping the partial termination symbols to one or more termination symbols; and receiving, at the CPE, the one or more termination symbols.
