A system for serializing input data signals and generating an output data signal includes a FIFO memory that launches the input data signals at different phases of a clock signal. The system further includes multiple stages of a serializer circuit, and each stage of the serializer circuit receives a clock signal. Each successive stage includes half the number of serializer circuits that are included in the previous stage, and each successive stage is clocked by a clock signal that transitions at twice the frequency of the previous stage clock signal. The serializer circuits that belong to a single stage receive the clock signal with different phase. The phase and frequency of clock signals of serializer stages are adjusted such that a launched input data signal is outputted as the output data signal. Further, a critical path for each serializer circuit is equal to full clock cycle of the clock signal.

A transmitter is configured to transmit a series of command signals and a series of data signals. The transmitter includes a serializer and a multiplexer. The serializer is configured to generate the series of data signals. The multiplexer, coupled to the serializer, is configured to selectively output the series of command signals or the series of data signals

Various aspects described herein relate to techniques for synchronization channel design and signaling in wireless communications systems (e.g., a 5th Generation (5G) New Radio (NR) system). In an aspect, a method includes identifying a frequency band supported by a user equipment (UE), identifying one or more frequency locations based on the identified frequency band, and the one or more frequency locations are a subset of synchronization raster points used for synchronization signal transmission. The method further includes searching for at least one synchronization signal based on the one or more identified frequency locations.

Novel tools and techniques are provided for implementing synchronization signal (“Sync Mark”) detection using multi-frequency sinusoidal (“MFS”) signal-based filtering. In various embodiments, a computing system may detect a location of a Sync Mark within a data signal, by using MFS signal-based filtering and a sliding window comprising successive search windows each having a bit length corresponding to a bit length of the Sync Mark to identify a portion of the data signal having a magnitude indicative of the Sync Mark. The computing system may refine the location of the Sync Mark within the data signal, by performing a phase measurement on the identified portion of the data signal having the magnitude indicative of the Sync Mark to identify a sub-portion of the identified portion of the data signal, the identified sub-portion having a phase indicative of the Sync Mark, the phase measurement being performed based on the MFS signal-based filtering.

The base station includes an encoder that encodes a first set of bits of MTC information with a first coding rate and encodes a second set of MTC information bits with a second coding rate. The first set and second set of bits are modulated using layered modulation and broadcast within the service area of the base station in a first transmission such that the first set of bits can be recovered using the low modulation order and the second set of bits can be recovered using the high modulation order. A relay station receives, demodulates and decodes the first transmission to recover at least the second set of bits. The relay station transmits a second set transmission including at least the second set of bits to at least one MTC device that did not recover the second set of bits from the first transmission.
